This patch fixes the bug which causes RSS to continue to work
after being disabled. After disabling RSS, traffic would continue
to be assigned to different queues instead of falling back to a
single queue. Without this patch, attempting to disable RSS would
not work as expected. This patch fixes the bug by clearing the
lookup table used by RSS such that all traffic is assigned to a
single queue. This patch also addresses the issue of reinstating
the lookup table should RSS then be re-enabled.

If a driver is unable to maintain all current user supplied settings
from ethtool (or other sources), it is not ok for a user request to
succeed and silently trample over previous configuration.
To that end, if you change the number of channels, it must not be
allowed to reduce the number of channels (queues) below the current
flow director filter rules targets. In this case, return -EINVAL when
a request to reduce the number of channels would do so. In addition
log a warning to the kernel buffer explaining why we failed, and report
the rules which prevent us from lowering the number of channels.

The i40e driver was causing a kernel panic when
non-contiguous Traffic Classes, or Traffic Classes not
starting with TC0, were configured on a link partner switch.
i40e does not support non-contiguous TCs.
To fix this, the patch changes the logic when determining
the total number of TCs enabled. Before, this would use the
highest TC number enabled and assume that all TCs below it were
also enabled. Now, we create a bitmask of enabled TCs and scan
it to determine not only the number of TCs, but also if the set
of enabled TCs starts at zero and is contiguous. If not, then
DCB is disabled by only returning one TC.

40GbE Intel Wired LAN Driver Updates 2016-07-22
This series contains updates to i40e and i40evf.
Heinrich Schuchardt found a possible null pointer being dereferenced in
i40e_debug_aq(), fixed the issue by doing the variable assignment after
we are sure the pointer is not null.
Avinash fixed an issue when link was down, we were not showing the
correct advertised link modes.
Mitch cleans up a useless initializer since the variable is assigned
right away. Refactors the receive filter handling to properly track
filter adds and deletes so the driver will not lose filters during a
reset and up/down cycles. Also added a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Catherine removes a device id which is not needed (or used). Moves
a mutex lock since we need to lock the client list around the
i40e_client_release() call to prevent the release from interrupting
the client instances while they are being added.
Joshua adds Hyper-V specific VF device ids.
Amitoj Kaur Chawla cleans up a redundant memset() call before a memcpy().
Stefan Assmann adds the missing link advertise for some x710 NICs.
Tushar Dave fixes and issue found on SPARC, where a PF reset clears MAC
filters and if a platform-specific MAC address is used, the driver has
to explicitly write default MAC address to MAC filters otherwise all
incoming traffic destined to the default MAC address will be dropped
after reset.

Properly track filter adds and deletes so the driver doesn't lose filters
during resets and up/down cycles. Add a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Implement a simple state machine so the driver can track the status of
each filter throughout its lifecycle. Properly manage the overflow promiscuous
state for the each VSI, and provide a way for the driver to detect when to exit
overflow promiscuous mode.
Remove all possible default MAC filters that the firmware may have set up so
that the driver can manage these correctly, particularly when VLANs come into
play. Remove the LAA flag for filters; instead just send whatever we get through
set_mac to the firmware as the LAA for wakeup purposes.
Finally, add the state of each filter to debugfs output so we can see what's
going on inside the driver's pointy little head.

Currently, the q_vector initialization routine sets the affinity_mask
of a q_vector based on v_idx value. Meaning a loop iterates on v_idx,
which is an incremental value, and the cpumask is created based on
this value.
This is a problem in systems with multiple logical CPUs per core (like in
SMT scenarios). If we disable some logical CPUs, by turning SMT off for
example, we will end up with a sparse cpu_online_mask, i.e., only the first
CPU in a core is online, and incremental filling in q_vector cpumask might
lead to multiple offline CPUs being assigned to q_vectors.
Example: if we have a system with 8 cores each one containing 8 logical
CPUs (SMT == 8 in this case), we have 64 CPUs in total. But if SMT is
disabled, only the 1st CPU in each core remains online, so the
cpu_online_mask in this case would have only 8 bits set, in a sparse way.
In general case, when SMT is off the cpu_online_mask has only C bits set:
0, 1*N, 2*N, ..., C*(N-1) where
C == # of cores;
N == # of logical CPUs per core.
In our example, only bits 0, 8, 16, 24, 32, 40, 48, 56 would be set.
This patch changes the way q_vector's affinity_mask is created: it iterates
on v_idx, but consumes the CPU index from the cpu_online_mask instead of
just using the v_idx incremental value.
No functional changes were introduced.

There are a couple of issues I found in i40e_rx_checksum while doing some
recent testing. As a result I have found the Rx checksum logic is pretty
much broken and returning that the checksum is valid for tunnels in cases
where it is not.
First the inner types are not the correct values to use to test for if a
tunnel is present or not. In addition the inner protocol types are not a
bitmask as such performing an OR of the values doesn't make sense. I have
instead changed the code so that the inner protocol types are used to
determine if we report CHECKSUM_UNNECESSARY or not. For anything that does
not end in UDP, TCP, or SCTP it doesn't make much sense to report a
checksum offload since it won't contain a checksum anyway.
This leaves us with the need to set the csum_level based on some value.
For that purpose I am using the tunnel_type field. If the tunnel type is
GRENAT or greater then this means we have a GRE or UDP tunnel with an inner
header. In the case of GRE or UDP we will have a possible checksum present
so for this reason it should be safe to set the csum_level to 1 to indicate
that we are reporting the state of the inner header.

Previously we were only looking at the FW supported PHY types if link
was down, because we want to be more specific when link is up. This
refactor changes this. When link is down, we still rely on the FW
supported PHY types, but when link is up, we select the possible
supported link modes from what we know about the current PHY type, and
AND that with the FW supported PHY types.

This patch adds priv-flag knob to configure global true promisc
support. With this patch the user can decide the flavor of
promiscuous that the VFs will see when promiscuous mode is enabled
on the interface. Since this a global setting for the whole device,
the priv-flag is exposed only on the first PF of the device.
The default is true promisc support is off, which means the promisc
mode for the VF will be limited/defport mode.
For the PF, we still will be in limited promisc unless in MFP mode
irrespective of the flavor picked through this knob.
Usage:
On PF0
ethtool --show-priv-flags p261p1
Private flags for p261p1:
MFP : off
LinkPolling : off
flow-director-atr : on
veb-stats : off
hw-atr-eviction : off
vf-true-promisc-support: off
to enable setting true promisc
ethtool --set-priv-flags p261p1 vf-true-promisc-support on
At this point if the VF is set to trust and promisc is enabled
on the VF through
ip link set ... promisc on
The VF/VFs will be able to see ALL ingress traffic

When testing on systems with very limited amounts of RAM, a bug was
found where, while changing the number of descriptors using ethtool,
the driver didn't test the limits of system memory before permanently
assuming it would be able to get receive buffer memory.
Work around this issue by pre-allocation of the receive buffer
memory, in the "ghost" ring, which is then used during reinit
using the new ring length.

benefit to the real driver of 16 byte descriptors, so drop a whole

Also since the previous patch made us use no-split mode all the
time, drop any support in the driver for any other value in dtype
and assume it is always zero (aka no-split).

This is part 1 of the Rx refactor series, just including
changes to i40e.
This refactor aligns the receive routine with the one in
ixgbe which was highly optimized. This reduces the code
we have to maintain and allows for (hopefully) more readable
and maintainable RX hot path.
In order to do this:
- consolidate the receive path into a single function that doesn't
use packet split but *does* use pages for Rx buffers.
- remove the old _1buf routine
- consolidate several routines into helper functions
- remove ethtool control over packet split

This patch makes it so that i40e and i40evf can use GSO_PARTIAL to support
segmentation for frames with checksums enabled in outer headers. As a
result we can now send data over these types of tunnels at over 20Gb/s
versus the 12Gb/s that was previously possible on my system.
The advantage with the i40e parts is that this offload is mostly
transparent as the hardware still deals with the inner and/or outer IPv4
headers so the IP ID is still incrementing for both when this offload is
performed.

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.

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.
