The feature flags list for i40e and i40evf is beginning to become pretty
massive. I plan to add another 4 or so features to these drivers and
duplicating the flags for each and every flags list is becoming a bit
repetitive.
The primary change here is that we now build our features list around
hw_encap_features. After that we assign that to vlan_features,
hw_features, and finally map that onto features. In addition we end up
throwing features onto hw_encap_features that end up having no effect such
as the Rx offloads and SCTP_CRC. However that should have no impact and
makes things a bit easier for us as hw_encap_features is one of the less
updated features maps available.
For i40evf I went through and sanity checked a few features as well.
Specifically RXCSUM was being set as a read-only feature which didn't make
much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag
since that is really a software feature and not a hardware one anyway so
disabling it is just a matter of ignoring the result from the hardware.

# ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000
querying for the rule shows the Action as 'Direct to queue 0'

Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.
This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.
Also default_vf_vlan_id and vlans_enabled were removed from the
vf_data_storage structure since they are not being used in the driver.

fm10k_io_error_detected() does not need to call pci_disable_device(). In
the cases where the reset needs to occur, the stack flow will result in
calling fm10k_remove() which already disables the PCI device. If we
leave the pci_disable_device(), we result in a warning about disabling
an already disabled device.
Many PCI drivers do call pci_disable_device() in their .error_detected()
routines, but it does not appear to be required. In addition, these
drivers have a check "is_pci_enabled()" call in their remove routines,
which is how they chose to handle the duplicate device disable.
This seems incorrect, since the PCI device structure is reference
counted. It is very possible that the reference count for the PCI device
could be greater than 1. In this case, you would remove the PCI device
within the error_detected routine, reducing count to 1, then remove it
again in the remove function, reducing it to zero. This would result in
yet another disable somewhere else failing. Thus, we shouldn't be using
is_pci_enabled() to check for this issue. Instead, just remove the
extraneous pci_device_disable() found within the error_detected routine.

switch manager has configured a port with zero bandwidth. Add support
for reading the fm10k_swapi_error structure from LPORT_MAP responses.
If the message contains the necessary TLV and has a non-zero error code,
report link down, clear the dglort_map, and delay the next
get_host_state call by a reasonable delay. Also log an error message
indicating that the LPORT_MAP request failed.
The delay ensures preventing an interrupt storm on the switch manager,
and reduces the number of mailbox messages we send in this scenario
drastically.

Multicast mode checking is no longer a requirement to perform unicast
and multicast address syncs. Specifically, a device operating in
promiscuous and/or all multicast mode is not excluded. The issue occurs
when the netdev is pre-configured to either multicast mode and is
enabled for the first time. The multicast-group table in the Switch
Manager will be missing obvious multicast entries associated to this
netdev.
Changes were also made to disallow unicast and multicast syncs with
VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry.
Requests with VLAN 0 by the netdev are only generated when the driver is
freshly installed and the default VID is not set.

This change fixes an (ab)use of the ethtool stats API, which could
result in corrupt memory or misleading stat output. The ethtool stats
API is not robust enough to handle varying number of statistics due to
how it requests the size and allocates memory. Remove the poorly conceived
support originally added for extra debug statistics. In the future,
a new stats API may open up the ability to display these statistics.

The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refector broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set.
We can't simply remove the check of the upper 16 bits and the call to
fm10k_iov_select vid, because this would remove the checks for default
VID and for ensuring no other VLANs can be enabled except pf_vid when it
has been set. To resolve that issue, this revision uses the
iov_select_vid when we have a single-bit update, and denies any
multi-bit update when the VLAN was administratively set by the PF. This
should be ok since the PF properly updates VLAN_TABLE when it assigns
the PF vid. This ensures that requests to add or remove the PF vid work
as expected, but a rogue VF could not use the multi-bit update as
a loophole to attempt receiving traffic on other VLANs.

This patch addresses a bug introduced based on my interpretation of the
XL710 datasheet. Specifically section 8.4.1 states that "A single transmit
packet may span up to 8 buffers (up to 8 data descriptors per packet
including both the header and payload buffers)." It then later goes on to
say that each segment for a TSO obeys the previous rule, however it then
refers to TSO header and the segment payload buffers.
I believe the actual limit for fragments with TSO and a skbuff that has
payload data in the header portion of the buffer is actually only 7
fragments as the skb->data portion counts as 2 buffers, one for the TSO
header, and one for a segment payload buffer.

Alex fixes igb where we were casting the MAC address as __beXX and then
passing it into le32_to_cpu, when we could simply cast as __lexx to

Doron Shikmoni fixes a bug in the output of "ethtool -m ethX" where
the data byte appeared duplicated.
Stefan fixes up e1000 and e1000e ethtool offline tests which were calling
dev_close() which causes IFF_UP to be cleared which removes teh interface
routes and some addresses, so use ndo_stop() instead.

These changes fix a problem where VF resets would get lost by the PF,

The 82544 has code that adds one additional descriptor per data buffer.
However we weren't taking that into account when determining the descriptors
needed for the next transmit at the end of the xmit_frame path.
This change takes that into account by doubling the number of descriptors
needed for the 82544 so that we can avoid a potential issue where we could
hang the Tx ring by loading frames with xmit_more enabled and then stopping
the ring without writing the tail.
In addition it adds a few more descriptors to account for some additional
workarounds that have been added over time.

The current code path is capable of grossly overestimating the number of
descriptors needed to transmit a new frame. This specifically occurs if
the skb contains a number of 4K pages. The issue is that the logic for
determining the descriptors needed is ((S) >> (X)) + 1. When X is 12 it
means that we were indicating that we required 2 descriptors for each 4K
page when we only needed one.
This change corrects this by instead adding (1 << (X)) - 1 to the S value
instead of adding 1 after the fact. This way we get an accurate descriptor
needed count as we are essentially doing a DIV_ROUNDUP().

40GbE Intel Wired LAN Driver Updates 2016-04-05
This series contains updates to i40e and i40evf only.
Stefan converts dev_close() to ndo_stop() for ethtool offline self test,
since dev_close() causes IFF_UP to be cleared which will remove the
interface routes and addresses.
Alex bumps up the size of the transmit data buffer to 12K rather than 8K,
which provides a gain in throughput and a reduction in overhead for
putting together the frame. Fixed an issue in the polling routines where
we were using bitwise operators to avoid the side effects of the
logical operators. Then added support for bulk transmit clean for skbs.
Jesse fixed a sparse issue in the type casting in the transmit code and
fixed i40e_aq_set_phy_debug() to use i40e_status as a return code.
Catherine cleans up duplicated code.
Shannon fixed the cleaning up of the interrupt handling to clean up the
IRQs only if we actually got them set up. Also fixed up the error
scenarios where we were trying to remove a non-existent timer or
worktask, which causes the kernel heartburn.
Mitch changes the notification of resets to the reset interrupt handler,
instead of the actual reset initiation code. This allows the VFs to get
properly notified for all resets, including resets initiated by different
PFs on the same physical device. Also moved the clearing of VFLR bit
after reset processing, instead of before which could lead to double
resets on VF init. Fixed code comment to match the actual function name.

From what I can tell the practical limitation on the size of the Tx data
buffer is the fact that the Tx descriptor is limited to 14 bits. As such
we cannot use 16K as is typically used on the other Intel drivers. However
artificially limiting ourselves to 8K can be expensive as this means that
we will consume up to 10 descriptors (1 context, 1 for header, and 9 for
payload, non-8K aligned) in a single send.
I propose that we can reduce this by increasing the maximum data for a 4K
aligned block to 12K. We can reduce the descriptors used for a 32K aligned
block by 1 by increasing the size like this. In addition we still have the
4K - 1 of space that is still unused. We can use this as a bit of extra
padding when dealing with data that is not aligned to 4K.
By aligning the descriptors after the first to 4K we can improve the
efficiency of PCIe accesses as we can avoid using byte enables and can fetch
full TLP transactions after the first fetch of the buffer. This helps to
improve PCIe efficiency. Below is the results of testing before and after
with this patch:
Recv Send Send Utilization Service Demand
Socket Socket Message Elapsed Send Recv Send Recv
Size Size Size Time Throughput local remote local remote
bytes bytes bytes secs. 10^6bits/s % S % U us/KB us/KB
Before:
87380 16384 16384 10.00 33682.24 20.27 -1.00 0.592 -1.00
After:
87380 16384 16384 10.00 34204.08 20.54 -1.00 0.590 -1.00
So the net result of this patch is that we have a small gain in throughput
due to a reduction in overhead for putting together the frame.

This patch adds support for generic Tx checksums to the ixgbevf driver. It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.
In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
MACLEN (maximum of 127), retrieved from:
skb_network_offset()
IPLEN (maximum of 511), retrieved from:
skb_checksum_start_offset() - skb_network_offset()
TUCMD.L4T indicates offset and if checksum or crc32c, based on:
skb->csum_offset
The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.
I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers. In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

While doing the work on igb I realized there were a few cases where we were
still adding VLANs to the VLVF entries for the PF when they were not
needed. This patch cleans that up so that the only time we add a PF entry
to the VLVF is either for VLAN 0 or if the PF has requested a VLAN that a VF
is already using.

The ATR code was assuming that it would be able to use tcp_hdr for
every TCP frame that came through. However this isn't the case as it
is possible for a frame to arrive that is TCP but sent through something
like a raw socket. As a result the driver was setting up bad filters in
which tcp_hdr was really pointing to the network header so the data was
all invalid.
In order to correct this I have added a bit of parsing logic that will
determine the TCP header location based off of the network header and
either the offset in the case of the IPv4 header, or a walk through the
IPv6 extension headers until it encounters the header that indicates
IPPROTO_TCP. In addition I have added checks to verify that the lowest
protocol provided is recognized as IPv4 or IPv6 to help mitigate raw
sockets using ETH_P_ALL from having ATR applied to them.

The VXLAN port number should be stored in network order instead of in host
order as it is accessed from the hot-path in ATR. This way we can avoid
having to do any byte swaps in order to validate the port number.
I moved the vxlan_port value into a hole in the read-mostly region of the
adapter struct. This way it should be in a warm cache-line instead of in
some isolated region in memory when it needs to be accessed.
In addition I went through and stripped a bunch of unneeded ifdef flags
since having an extra variable present doesn't really hurt anything and
makes the code easier to read. I also went through and dropped the
NETIF_F_RXCSUM flag which was being set in hw_encap_features but provides
no value as the flag is not evaluated in the Rx path.

Pull more rdma updates from Doug Ledford:
"Round two of 4.6 merge window patches.
This is a monster pull request. I held off on the hfi1 driver updates
(the hfi1 driver is intimately tied to the qib driver and the new
rdmavt software library that was created to help both of them) in my
first pull request. The hfi1/qib/rdmavt update is probably 90% of
this pull request. The hfi1 driver is being left in staging so that
it can be fixed up in regards to the API that Al and yourself didn't
like. Intel has agreed to do the work, but in the meantime, this
clears out 300+ patches in the backlog queue and brings my tree and
their tree closer to sync.
This also includes about 10 patches to the core and a few to mlx5 to
create an infrastructure for configuring SRIOV ports on IB devices.
That series includes one patch to the net core that we sent to netdev@
and Dave Miller with each of the three revisions to the series. We
didn't get any response to the patch, so we took that as implicit
approval.
Finally, this series includes Intel's new iWARP driver for their x722
cards. It's not nearly the beast as the hfi1 driver. It also has a
linux-next merge issue, but that has been resolved and it now passes
just fine.

The success of CMA allocation largely depends on the success of
migration and key factor of it is page reference count. Until now, page
reference is manipulated by direct calling atomic functions so we cannot
follow up who and where manipulate it. Then, it is hard to find actual
reason of CMA allocation failure. CMA allocation should be guaranteed
to succeed so finding offending place is really important.
In this patch, call sites where page reference is manipulated are
converted to introduced wrapper function. This is preparation step to
add tracepoint to each page reference manipulation function. With this
facility, we can easily find reason of CMA allocation failure. There is
no functional change in this patch.
In addition, this patch also converts reference read sites. It will
help a second step that renames page._count to something else and
prevents later attempt to direct access to it (Suggested by Andrew).

Modern Intel systems supports cross timestamping of the network device
clock and Always Running Timer (ART) in hardware. This allows the
device time and system time to be precisely correlated. The timestamp
pair is returned through e1000e_phc_get_syncdevicetime() used by
get_system_device_crosststamp(). The hardware cross-timestamp result
is made available to applications through the PTP_SYS_OFFSET_PRECISE
ioctl which calls e1000e_phc_getcrosststamp().

relaxes the test to only check the type to make it equivalent
to the check before I broke it. With this the old instantiation
continues to work.
A good smoke test is to setup mqprio with,

Offloading is switched on by default:

rx-vlan-offload: on
tx-vlan-offload: on
$ ping -c 3 -I eth0.42 192.168.42.2

Now switch off VLAN offloading and try again:
$ ethtool -K eth0 rxvlan off
Actual changes:
rx-vlan-offload: off

I can only reproduce it on an i350, the above works fine on a 82580.
While inspecting the igb source, I came across the code in igb_set_vmolr
which sets the E1000_VMOLR_STRVLAN/E1000_DVMOLR_STRVLAN flags once and
for all, and in all of the igb code there's no other place where the
STRVLAN is set or cleared. Thus, VLAN stripping is enabled in igb
unconditionally, independently of the offloading setting.
I compared that to the latest Intel igb-5.3.3.5 driver from
http://sourceforge.net/projects/e1000/ which in fact sets and clears the
STRVLAN flag independently from igb_set_vmolr in its own function
igb_set_vf_vlan_strip, depending on the vlan settings.
So I included the STRVLAN handling from the igb-5.3.3.5 driver into our
current igb driver and tested the above scenario again. This time ping
still works after switching off VLAN offloading.
Tested on i350, with and without addtional VFs, as well as on 82580
successfully.

A similar issue was addressed a few years ago in the following thread:
http://www.spinics.net/lists/netdev/msg245877.html
At that time there were concerns that removing this statement may cause other
side effects. However the submitter addressed those concerns. But the dialogue
went cold. We have a new case where a customers application is registering and
un-registering multicast addresses every few seconds. This is leading to many
"Link is Up" messages in the logs as a result of the
"netif_carrier_off(netdev)" statement called by igbvf_msix_other(). Also on
some kernels it is interfering with the bonding driver causing it to failover
and subsequently affecting connectivity.
The Sourgeforge driver does not make this call and is therefore not affected.
If there were any side effects I would expect that driver to also be affected.
I have tested re-loading the igbvf driver and downing the adapter with the PF
entity on the host where the VM has this patch. When I bring it back up again
connectivity is restored as expected. Therefore I request that this patch gets
submitted.

This patch adds support for generic Tx checksums to the igbvf driver. It
turns out this is actually pretty easy after going over the datasheet as we
were doing a number of steps we didn't need to.
In order to perform a Tx checksum for an L4 header we need to fill in the
following fields in the Tx descriptor:
MACLEN (maximum of 127), retrieved from:
skb_network_offset()
IPLEN (maximum of 511), retrieved from:
skb_checksum_start_offset() - skb_network_offset()
TUCMD.L4T indicates offset and if checksum or crc32c, based on:
skb->csum_offset
The added advantage to doing this is that we can support inner checksum
offloads for tunnels and MPLS while still being able to transparently
insert VLAN tags.
I also took the opportunity to clean-up many of the feature flag
configuration bits to make them a bit more consistent between drivers. In
the case of the VF drivers this meant adding support for SCTP CRCs, and
inner checksum offloads for MPLS and various tunnel types.

In general case the maximum supported half cycle time of the synchronized
output clock is 70msec. Slower half cycle time than 70msec can be
programmed also as long as the output clock is synchronized to whole
seconds, useful specifically for generating a 1Hz clock.
Permitted values for the clock half cycle time are: 125,000,000 decimal,
250,000,000 decimal and 500,000,000 decimal (equals to 125msec, 250msec
and 500msec respectively).
Before this patch, only the half cycle time of less than or equal to 70msec
uses the I210 clock output function. This patch adds additional conditions
when half cycle time is equal to 125msec or 250msec or 500msec to use
clock output function.
Under other conditions, interrupt driven target time output events method
is still used to generate the desired clock output.

This patch is meant to rewrite the logic for how we determine if we can
transmit the frame or if it needs to be linearized.
The previous code for this function was using a mix of division and modulus
division as a part of computing if we need to take the slow path. Instead
I have replaced this by simply working with a sliding window which will
tell us if the frame would be capable of causing a single packet to span
several descriptors.
The logic for the scan is fairly simple. If any given group of 6 fragments
is less than gso_size - 1 then it is possible for us to have one byte
coming out of the first fragment, 6 fragments, and one or more bytes coming
out of the last fragment. This gives us a total of 8 fragments
which exceeds what we can allow so we send such frames to be linearized.
Arguably the use of modulus might be more exact as the approach I propose
may generate some false positives. However the likelihood of us taking much
of a hit for those false positives is fairly low, and I would rather not
add more overhead in the case where we are receiving a frame composed of 4K
pages.

identified the type.
The advantage to this approach is that we can assemble values as we go

result we can significantly clean up the tunneling configuration for
instance as we can just do a pointer walk and do the math for the distance

The Tx checksum path was maintaining a set of 3 pointers and two lengths in
order to prepare the packet for being checksummed. The thing is we only
really needed 2 pointers, and the lengths that were being maintained can
easily be computed.
As such we can replace the IPv4 and IPv6 header pointers with one single
union that represents both, or a generic pointer to the start of the
network header. For the L4 headers we can do the same with TCP and a
generic pointer to the start of the transport header. The length of the
TCP header is obtained by simply multiplying doff by 4, and the network
header length can be obtained by subtracting the network header pointer
from the transport header pointer.
While I was at it I renamed l4_hdr to l4_proto to make it a bit more clear
and less likely to be confused with l4.hdr which is the transport header
pointer.

function. The general idea here is that we should only be updating the
header after we verify we have completed a skb_cow_head check to verify the
head is writable.
One other advantage to doing this is that it makes things much more
obvious. For example, in the case of IPv6 there was one spot where the
offset of the IPv4 header checksum was being updated which is obviously
incorrect.

This patch makes it so that the L4 header offsets and such can be ignored
when dealing with the L3 checksum and length update. This is done making
use of two things.
First we can just use the offset from the L4 header to the start of the
packet to determine the L4 offset, and from that we can then make use of
the data offset to determine the full length of the headers.
As far as adjusting the checksum to remove the length we can simply add the
inverse of the length instead of having to recompute the entire
pseudo-header without the length. In the case of an IPv6 header this
should be significantly cheaper since we can make use of a value we already
needed instead of having to read the source and destination address out of
the packet.

The i40e and i40evf drivers contained code for inserting an outer checksum
on UDP tunnels. The issue however is that the upper levels of the stack
never requested such an offload and it results in possible errors.
In addition the same logic was being applied to the Rx side where it was
attempting to validate the outer checksum, but the logic there was
incorrect in that it was testing for the resultant sum to be equal to the
header checksum instead of being equal to 0.
Since this code is so massively flawed, and doing things that we didn't ask
for it to do I am just dropping it, and will bring it back later to use as
an offload for SKB_GSO_UDP_TUNNEL_CSUM which can make use of such a
feature.
As far as the Rx feature I am dropping it completely since it would need to
be massively expanded and applied to IPv4 and IPv6 checksums for all parts,
not just the one that supports Tx checksum offload for the outer.

In MFP mode particularly when we were setting the PF VSI in limited
promiscuous, the HW switch was still mirroring the outgoing packets
from other VSIs (VF/VMdq) onto the PF VSI.
With this new bit set, the mirroring doesn't happen any more and so
we are in limited promiscuous on the PF VSI in MFP which is similar
to defport.
An API check is not required, since this bit is reserved for FW API

In the case where we have a page fully used by receive data, we need to
release the page fully to the stack. Instead of calling get_page (which
increments the page count) followed by free_page (which decrements the
page count), just donate our reference to the stack. Although this
donation is not tax deductible, it does allow us to avoid two very
expensive atomic operations that reverse each other.

This patch falls back to enabling unicast, multicast and
broadcast promiscuous mode when the driver must disable it's use
of "default port" aka defport mode (which is normally used to
provide a promiscuous mode), due to internal incompatibility
with Multiple Function per Port (aka MFP).
The situation that requires this patch is when Physical
Function 0 is the device being used, and it can support SR-IOV
when MFP is enabled, via the driver creating a VEB on an MFP
enabled adapter.

interrupts that got lost but WB happened.
If that happens without this patch we will see a tx_timeout.
To work around it, this patch goes ahead and reschedules NAPI
in that situation, if NAPI is not already scheduled.
We also add a counter in ethtool to keep track of when
we detect a case of tx_lost_interrupt.
Note: napi_reschedule() can be safely called from process/service_task

====================
40GbE Intel Wired LAN Driver Updates 2016-02-17
This series contains updates to i40e/i40evf only (again).
Jesse moves sync_vsi_filters() up in the service_task because it may need
to request a reset, and we do not want to wait another round of service
task time. Refactored the enable_icr0() in order to allow it to be
decided by the caller whether the CLEARPBA (clear pending events) bit will
be set while re-enabling the interrupt. Also provides the "Don't Give Up"
patch, where the driver will keep polling trying to allocate receive buffers
until it succeeds. This should keep all receive queues running even in
the face of memory pressure. Cleans up the debugging helpers by putting
everything in hex to be consistent.
Neerav updates the DCB firmware version related checkes specific to X710
and XL710 only since the checks are not required for X722 devices.
Shannon adds the use of the new shared MAC filter bit for multicast and
broadcast filters in order to make better use of the filters available
from the device. Added a parameter to allow the driver to set the
enable/disable of statistics gathering in the hardware switch. Also the
L2 cloud filtering parameter is removed since it was never used.
Anjali refactors the force_wb and WB_ON_ITR functionality since
Force-WriteBack functionality in X710/XL710 devices has been moved out of
the clean routine and into the service task, so we need to make sure
WriteBack-On-ITR is separated out since it is still called from clean.
Catherine changes the VF driver string to reflect all the products that
are supported.
Mitch refactors the packet split receive code to properly use half-pages
for receives. Also changes the use of bitwise operators to logical
operators on clean_complete variable, while making a witty reference to
Mr. Spock. Cleans up (i.e. removes) the hsplit field in the ring
structure and use the existing macro to detect packet split enablement,
which allows debugfs dumps of the VSI to properly show which recevie
routine is in use.

Increment the page use count each time we give a half-page to an skb,

we need it again. Only free and reallocate pages if the count shows that
both half-pages are in use. Add counters to track reallocations and page

This series contains updates to i40e/i40evf only.
Shannon adds flags to MAC allocation requests to signify that the MAC VLAN
filters should come from the shared resource pool. Added a new "set switch

more bits of netdev data into the debugfs output for dump VSI.
Pandi fixes the width of two datatypes which were being declared a different
size from what they are assigned.
Anjali fixes an issue where we were not doing write-back on interrupt
throttle for legacy case in x722.
Mitch adds a counter for ARQ overflows since sometimes an ever-growing
number indicates that something bad is happening. Also added 20G speed for
Tx bandwidth calculations.
Jesse refactors the DCB function based on a community suggestion to change
the multi-level if statement into a switch statement. Cleans up VF device
IDs in the PF, since it does not need to know them.

This patch ensures ixgbe will not try to offload hash tables from the
u32 module. The device class does not currently support this so until
it is enabled just abort on these tables.
Interestingly the more flexible your hardware is the less code you
need to implement to guard against these cases.

This adds initial support for offloading the u32 tc classifier. This
initial implementation only implements a few base matches and actions
to illustrate the use of the infrastructure patches.
However it is an interesting subset because it handles the u32 next
hdr logic to correctly map tcp packets from ip headers using the ihl
and protocol fields. After this is accepted we can extend the match
and action fields easily by updating the model header file.
Also only the drop action is supported initially.
Here is a short test script,
#tc qdisc add dev eth4 ingress
#tc filter add dev eth4 parent ffff: protocol ip \
u32 ht 800: order 1 \
match ip dst 15.0.0.1/32 match ip src 15.0.0.2/32 action drop
<-- hardware has dst/src ip match rule installed -->
#tc filter del dev eth4 parent ffff: prio 49152
#tc filter add dev eth4 parent ffff: protocol ip prio 99 \

This adds an ixgbe data structure that is used to determine what
headers:fields can be matched and in what order they are supported.
For hardware devices this can be a bit tricky because typically
only pre-programmed (firmware, ucode, rtl) parse graphs will be
supported and we don't yet have an interface to change these from
the OS. So its sort of a you get whatever your friendly vendor
provides affair at the moment.
In the future we can add the get routines and set routines to
update this data structure. One interesting thing to note here
is the data structure here identifies ethernet, ip, and tcp
fields without having to hardcode them as enumerations or use
other identifiers.

1GbE Intel Wired LAN Driver Updates 2016-02-15
This series contains updates to igb only.
Shota Suzuki cleans up unnecessary flag setting for 82576 in
igb_set_flag_queue_pairs() since the default block already sets
IGB_FLAG_QUEUE_PAIRS to the correct value anyways, so the e1000_82576
code block is not necessary and we can simply fall through. Then fixes
an issue where IGB_FLAG_QUEUE_PAIRS can now be set by using "ethtool -L"
option but is never cleared unless the driver is reloaded, so clear the
queue pairing if the pairing becomes unnecessary as a result of "ethtool
-L".
Mitch fixes the igbvf from giving up if it fails to get the hardware
mailbox lock. This can happen when the PF-VF communication channel is
heavily loaded and causes complete communications failure between the
PF and VF drivers, so add a counter and a delay so that the driver will
now retry ten times before giving up on getting the mailbox lock.
The remaining patches in the series are from Alex Duyck, starting with the
cleaning up code that sets the MAC address. Then refactors the VFTA and
VLVF configuration, to simplify and update to similar setups in the ixgbe
driver. Fixed an issue were VLANs headers size was being added to the
value programmed into the RLPML registers, yet these registers already
take into account the size of the VLAN headers when determining the
maximum packet length, so we can drop the code that adds the size to
the RLPML registers. Cleaned up the configuration of the VF port based
VLAN configuration. Also fixed the igb driver so that we can fully
support SR-IOV or the recently added NTUPLE filtering while allowing
support for VLAN promiscuous mode. Also added the ability to use the
bridge utility to add a FDB entry for the PF to an igb port.

There was a workaround partially implemented for the 82576 that is needed
in order for VLAN tag stripping to function correctly. The original code
had side effects that would make it so the workaround was active on all
MACs. I have updated the code so that the workaround is enabled, but
limited to the 82576, or activated if we exceed the available unicast
addresses.
The workaround has a side effect of mirroring all of the traffic outgoing
from the VFs back to the PF. As such it is not recommended to use the
82576 in promiscuous mode as it will take a performance hit, though this is
now consistent with the performance as seen on the out-of-tree igb driver.
I also limited the scope of the UTA bits all being set to only when the
VMOLR register is enabled. This should limit the effects of the UTA
register so that we don't pick up any excess traffic unless promiscuous
mode has been enabled on the PF, whereas before the PF would have ended up
in something equivalent to unicast promiscuous mode with VLAN filtering
otherwise.

In some modes, bonding would not enslave VF interfaces. This is due to
bonding calling change_mtu and the immediately calling open. Because of
the asynchronous nature of the admin queue mechanism, the VF returns
-EBUSY to the open call, because it knows the previous operation hasn't
finished yet. This causes bonding to fail with a less-than-useful error
message.
To fix this, remove the check for pending operations at the beginning of
open. But this introduces a new bug where the driver will panic on a
quick close/open cycle. To fix that, we add a new driver state,
__I40EVF_DOWN_PENDING, that the driver enters when down is called. The
driver finally transitions to a fully DOWN state when it receives
confirmation from the PF driver that all the queues are disabled. This
allows open to complete even if there is a pending mtu change, and
bonding is finally happy.

10GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to ixgbe only.
Vasu provides three fixes for ixgbe, first assigns a minimum credit to
a traffic class to resolve a Tx hang for CEE mode configuration. Second
fix changes the driver to use netdev->fcoe_ddp_xid instead of our local
IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices
and avoids a DDP skip error on X550. Lastly fix the PFC configuration
to include X550 devices.
Emil provides a fix for reporting the speed in ethtool by using the
stored value in out adapter structure. This is due to external drivers
may end up with unknown speed when calling ethtool_get_settings().
Mark fixes the handling of any outer UDP checksum, by passing the
skb up with CHECKSUM_NONE when an outer UDP checksum is set. This
will cause the stack to check the checksum, also do not increment an
error counter because we do not really know if there is an actual error.
Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being
performed on such packets. Fix this by skipping extended headers
when they are present.
Usha fixes an issue with X550 and getting FDMI HBA attributes when
FCoE support is enabled.
Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which
the hardware generates MDD events. Resolve this by setting the expected
values in the transmit context descriptors for FCoE/FIP frames and
adding a flush after writing the RDLEN register.

Right now ATR is not handling IPv6 extended headers, so ATR is not
being performed on such packets. Fix that by skipping extended
headers when they are present. This also fixes a problem where
the ATR code was not checking that the inner protocol was actually
TCP before setting up the signature rules. Since the protocol check
is intimately involved with the extended header processing as well,
this all gets fixed together.

In ixgbe_get_settings() the link status and speed of the interface
are determined based on a read from the LINKS register via the call
to mac.ops.check.link(). This can cause issues where external drivers
may end up with unknown speed when calling ethtool_get_setings().
Instead of calling the mac.ops.check_link() we can report the speed
from the adapter structure which is populated by the driver.

If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded
in hardware. So the Stack doesn't do a SW hash which is required
for load balancing if the user decides to turn of rx-hashing
on our device.
This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

This is the i40e equivalent of commit c762dff24c ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").
As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.
In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.
The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.

When I had rewritten the code for ixgbe_clear_vf_vlans() it looks like I
had transitioned back and forth between using word as an offset and using
word as a register offset. As a result I honestly don't see how the code
was working before other than the fact that resetting the VLANs on the VF
like didn't do much to clear them.
Another issue found is that the mask was using a divide instead of a
modulus. As a result the mask bit was incorrectly being set to either bit
0 or 1 based on the value of the VF being tested. As a result the wrong
VFs were having their VLANs cleared if they were enabled.
I have updated the code so that word represents the offset in the array.
This way we can use the modulus and xor operations and they will make sense
instead of being performed on a 4 byte aligned value.
I replaced the statement "(word % 2) ^ 1" with "~word % 2" in order to
reduce the line length as the line exceeded 80 characters with the register
name inserted. The two should be equivalent so the change should be safe.

This patch is meant to cleanup the exception handling for the paths where
we reset the interrupts and then reconfigure them. In all of these paths
we had very different levels of exception handling. I have updated the
driver so that all of the paths should result in a similar state if we
fail.
Specifically the driver will now unload the mailbox interrupt, free the
queue vectors and MSI-X, and then detach the interface.
In addition for any of the PCIe related resets I have added a check with
the hw_ready function to just make sure the registers are in a readable
state prior to reopening the interface.

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.
This patch:
- Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
NETIF_F_ALL_CSUM is being used as a mask).
- Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to

The SCTP checksum is really a CRC and is very different from the
standards 1's complement checksum that serves as the checksum
for IP protocols. This offload interface is also very different.
Rename NETIF_F_SCTP_CSUM to NETIF_F_SCTP_CRC to highlight these
differences. The term CSUM should be reserved in the stack to refer
to the standard 1's complement IP checksum.

Since the introduction of 82574 support in e1000e, the driver has worked
on the assumption that msi-x interrupt generation is automatically
disabled after each irq. As it turns out, this is not the case.
Currently, rx interrupts can fire multiple times before and during napi
processing. This can be a problem for users because frames that arrive
in a certain window (after adapter->clean_rx() but before
napi_complete_done() has cleared NAPI_STATE_SCHED) generate an interrupt
which does not lead to napi_schedule(). These frames sit in the rx queue
until another frame arrives (a tcp retransmit for example).
While the EIAC and CTRL_EXT registers are properly configured for irq
automask, the modification of IAM in e1000_configure_msix() is what
prevents automask from working as intended.
This patch removes that erroneous write and fixes interrupt rearming for
tx interrupts. It also clears IAME from CTRL_EXT. This is not strictly
necessary for operation of the driver but it is to avoid disruption from
potential programs that access the registers directly, like `ethregs -c`.

====================
1GbE Intel Wired LAN Driver Updates 2015-12-12
This series contains updates to e1000, e1000e and igb.
Joern Engel fixes up the e1000 driver to reduce scheduler latencies by
making the eeprom read/write functions scheduler friendly by using a mutex
lock instead of a spin lock.
Todd adds code for igb to initialize the 88E1543 PHY properly. Then fixed
igb to use the correct i210 register for EEMNGCTL, since the i210 has two
EEPROM access registers (EEARBC and EEMNGCTL).
Dmitry Vyukov provides a fix for e1000 to resolve a data race found with
KernelThreadSanitizer (KTSAN), where no memory barriers were being used
when buffers get recycled, so the recycled buffers can be corrupted. So
use smp_store_release() to update tx_ring->next_to_clean and
smp_load_acquire() to read tx_ring->next_to_clean to properly hand off
buffers from e1000_clean_tx_irq() to e1000_xmit_frame().
Jarod Wilson fixes igb so that we do not try to unmap a NULL hw_addr. Then
cleaned up array_rd32() so that it uses igb_rd32() the same as rd32() and
use io_addr() in more places so that we do not have to call E1000_REMOVED().
Janusz Wolak cleans up the e1000 driver by correcting warnings produced
by checkpatch.pl for the driver.
Jean Sacren provides several patches with general cleanups for e1000 and
e1000e, which include code comment fix-ups and cleanup of local variables
not needed.
Dmitry Fleytman fixes a possible division by zero in the receive interrupt
handler for e1000e when working without adaptive interrupt moderation,
which is typically disabled on jumbo MTUs.
Raanan increases the timeout of the polling bit due to timing changes to
the ME firmware on a platform, so increase the timeout to 300ms. Added
initial support for i219-LM, which is a LOM that will be available on
systems with the Lewisburg Platform Controller HUB (PCH) chipset.
Jan Beulich fixes a NULL dereference in igb, due to the adapter->vf _data
being NULL while adapter->vfs_allocated_count is non-zero.

The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV
during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the
right number of queues") causes VFs no longer getting set up, leading
to NULL pointer dereferences due to the adapter's ->vf_data being NULL
while ->vfs_allocated_count is non-zero. The first commit not only
neglected the side effect of igb_sriov_reinit() that the second commit
tried to account for, but also that of setting IGB_FLAG_HAS_MSIX,
without which igb_enable_sriov() is effectively a no-op. Calling
igb_{,re}set_interrupt_capability() as done here seems to address this,
but I'm not sure whether this is better than sinply reverting the other
two commits.

This patch guarantees that the VFs do not have access to VLANs that they
were not supposed to. What this patch does is add code so that we delete
the previous port VLAN after adding a new one, and if we reset the VF we
clear all of the filters associated with it.
Previously the code was leaving all previous VLANs mapped to the VF and
they didn't get deleted unless the VF specifically requested it or if the
PF itself was reset.

This patch makes certain that we clear the pool mappings added when we
configure default MAC addresses for the interface. Without this we run the
risk of leaking an address into pool 0 which really belongs to VF 0 when
SR-IOV is enabled.

This patch is a follow-on for enabling VLAN promiscuous and allowing the PF
to add VLANs without adding a VLVF entry. What this patch does is go
through and free the VLVF registers if they are not needed as the VLAN
belongs only to the PF which is the default pool.

This patch adds support for VLAN promiscuous with SR-IOV enabled.
The code prior to this patch was only adding the PF to VLANs that the VF
had added. As such enabling promiscuous mode would actually not add any
additional VLAN filters so visibility was limited. This lead to a number
of issues as the bridge and OVS would expect us to accept all VLAN tagged
packets when promiscuous mode was enabled, and instead we would filter out
most if not all depending on the configuration of the PF.
With this patch what we do is set all the bits in the VFTA and all of the
VLVF bits associated with the pool belonging to the PF. By doing this the
PF is guaranteed to receive all VLAN tagged traffic associated with the RAR
filters assigned to the PF. In addition we will clean up those same bits
in the event of promiscuous mode being disabled.

This patch is meant to reduce the complexity of the search function used
for finding a VLVF entry associated with a given VLAN ID. The previous
code was searching from bottom to top. I reordered it to search from top
to bottom. In addition I pulled an AND statement out of the loop and
instead replaced it with an OR statement outside the loop. This should
help to reduce the overall size and complexity of the function.
There was also some formatting I cleaned up in regards to whitespace and
such.

This patch adds support for bypassing the VLVF entry creation when the PF
is adding a new VLAN. The advantage to doing this is that we can then save
the VLVF entries for the VFs which must have them in order to function,
versus the PF which can fall back on the default pool entry.

This patch addresses several issues within the VLVF and VLVFB
configuration
First was the fact that code was overly complicated with multiple
conditional paths depending on if we adding or removing and which bit we
were going to add or remove. Instead of messing with all that I have
simplified it by using (vid / 32) and (1 - vid / 32) to identify our
register and the other vlvfb register.
Second was the fact that we were likely leaking a few packets into the PF
in cases where we were deleting an entry and the VFTA filter for that entry
as the ordering was such that we deleted the pool and then the VLAN filter
instead of the other way around. I have updated that by adding a check for
no bits being set and if that occurs we clear things up in the proper
order.

In order to clear the way for upcoming work I thought it best to drop the
level of indent in the ixgbe_set_vfta_generic function. Most of the code
is held in the virtualization specific section. So the easiest approach is
to just add a jump label and jump past the bulk of the code if it is not
enabled.

This patch simplifies the logic for setting the VFTA register by removing
the number of conditional checks needed. Instead we just use some boolean
logic to generate vfta_delta, and if that is set then we xor the vfta by
that value and write it back.

The code for checking the PF bit in ixgbe_set_vf_vlan_msg was using the
wrong offset and as a result it was pulling the VLAN off of the PF even if
there were VFs numbered greater than 40 that still had the VLAN enabled.

Add a check to make certain mac_table was actually allocated and is not
NULL. If it is NULL return -ENOMEM and allow the probe routine to fail
rather then causing a NULL pointer dereference further down the line.
