48079e7fdd ibmvnic: don't spin in tasklet
ibmvnic_tasklet() continuously spins waiting for responses to all
capability requests. It does this to avoid encountering an error
during initialization of the vnic. However if there is a bug in the
VIOS and we do not receive a response to one or more queries the
tasklet ends up spinning continuously leading to hard lock ups.

If we fail to receive a message from the VIOS it is reasonable to
timeout the login attempt rather than spin indefinitely in the tasklet.

151b6a5c06 ibmvnic: init ->running_cap_crqs early
We use ->running_cap_crqs to determine when the ibmvnic_tasklet() should
send out the next protocol message type. i.e when we get back responses
to all our QUERY_CAPABILITY CRQs we send out REQUEST_CAPABILITY crqs.
Similiary, when we get responses to all the REQUEST_CAPABILITY crqs, we
send out the QUERY_IP_OFFLOAD CRQ.

We currently increment ->running_cap_crqs as we send out each CRQ and
have the ibmvnic_tasklet() send out the next message type, when this
running_cap_crqs count drops to 0.

This assumes that all the CRQs of the current type were sent out before
the count drops to 0. However it is possible that we send out say 6 CRQs,
get preempted and receive all the 6 responses before we send out the
remaining CRQs. This can result in ->running_cap_crqs count dropping to
zero before all messages of the current type were sent and we end up
sending the next protocol message too early.

Instead initialize the ->running_cap_crqs upfront so the tasklet will
only send the next protocol message after all responses are received.

Use the cap_reqs local variable to also detect any discrepancy (either
now or in future) in the number of capability requests we actually send.

Currently only send_query_cap() is affected by this behavior (of sending
next message early) since it is called from the worker thread (during
reset) and from application thread (during ->ndo_open()) and they can be
preempted. send_request_cap() is only called from the tasklet  which
processes CRQ responses sequentially, is not be affected.  But to
maintain the existing symmtery with send_query_capability() we update
send_request_capability() also.

db9f0e8bf7 ibmvnic: Allow extra failures before disabling
If auto-priority-failover (APF) is enabled and there are at least two
backing devices of different priorities, some resets like fail-over,
change-param etc can cause at least two back to back failovers. (Failover
from high priority backing device to lower priority one and then back
to the higher priority one if that is still functional).

Depending on the timimg of the two failovers it is possible to trigger
a "hard" reset and for the hard reset to fail due to failovers. When this
occurs, the driver assumes that the network is unstable and disables the
VNIC for a 60-second "settling time". This in turn can cause the ethtool
command to fail with "No such device" while the vnic automatically recovers
a little while later.

Given that it's possible to have two back to back failures, allow for extra
failures before disabling the vnic for the settling time.

bf25146a55 bpf: add frags support to the bpf_xdp_adjust_tail() API
This change adds support for tail growing and shrinking for XDP frags.

When called on a non-linear packet with a grow request, it will work
on the last fragment of the packet. So the maximum grow size is the
last fragments tailroom, i.e. no new buffer will be allocated.
A XDP frags capable driver is expected to set frag_size in xdp_rxq_info
data structure to notify the XDP core the fragment size.
frag_size set to 0 is interpreted by the XDP core as tail growing is
not allowed.
Introduce __xdp_rxq_info_reg utility routine to initialize frag_size field.

When shrinking, it will work from the last fragment, all the way down to
the base buffer depending on the shrinking size. It's important to mention
that once you shrink down the fragment(s) are freed, so you can not grow
again to the original size.

This was caused by PF queue pile fragmentation due to
flow director VSI queue being placed right after main VSI.
Because of this main VSI was not able to resize its
queue allocation for XDP resulting in no queues allocated
for main VSI when XDP was turned on.

Fix this by always allocating last queue in PF queue pile
for a flow director VSI.

d701658a50 i40e: Fix issue when maximum queues is exceeded
Before this patch VF interface vanished when
maximum queue number was exceeded. Driver tried
to add next queues even if there was not enough
space. PF sent incorrect number of queues to
the VF when there were not enough of them.

Add an additional condition introduced to check
available space in 'qp_pile' before proceeding.
This condition makes it impossible to add queues
if they number is greater than the number resulting
from available space.
Also add the search for free space in PF queue
pair piles.

Without this patch VF interfaces are not seen
when available space for queues has been
exceeded and following logs appears permanently
in dmesg:
"Unable to get VF config (-32)".
"VF 62 failed opcode 3, retval: -5"
"Unable to get VF config due to PF error condition, not retrying"

1771afd474 net: cpsw: avoid alignment faults by taking NET_IP_ALIGN into account
Both versions of the CPSW driver declare a CPSW_HEADROOM_NA macro that
takes NET_IP_ALIGN into account, but fail to use it appropriately when
storing incoming packets in memory. This results in the IPv4 source and
destination addresses to appear misaligned in memory, which causes
aligment faults that need to be fixed up in software.

So let's switch from CPSW_HEADROOM to CPSW_HEADROOM_NA where needed.
This gets rid of any alignment faults on the RX path on a Beaglebone
White.

2d19c3fd80 net: axienet: increase default TX ring size to 128
With previous changes to make the driver handle the TX ring size more
correctly, the default TX ring size of 64 appears to significantly
bottleneck TX performance to around 600 Mbps on a 1 Gbps link on ZynqMP.
Increasing this to 128 seems to bring performance up to near line rate and
shouldn't cause excess bufferbloat (this driver doesn't yet support modern
byte-based queue management).

bb193e3db8 net: axienet: fix for TX busy handling
Network driver documentation indicates we should be avoiding returning
NETDEV_TX_BUSY from ndo_start_xmit in normal cases, since it requires
the packets to be requeued. Instead the queue should be stopped after
a packet is added to the TX ring when there may not be enough room for an
additional one. Also, when TX ring entries are completed, we should only
wake the queue if we know there is room for another full maximally
fragmented packet.

Print a warning if there is insufficient space at the start of start_xmit,
since this should no longer happen.

Combined with increasing the default TX ring size (in a subsequent
patch), this appears to recover the TX performance lost by previous changes
to actually manage the TX ring state properly.

since a slot which had been loaded with transmit data but the device had

causing non-transmitted slots to be overwritten. The control field in

only be updated when the device completes the entry).

04cc2da396 net: axienet: reset core on initialization prior to MDIO access
In some cases where the Xilinx Ethernet core was used in 1000Base-X or
SGMII modes, which use the internal PCS/PMA PHY, and the MGT
transceiver clock source for the PCS was not running at the time the
FPGA logic was loaded, the core would come up in a state where the
PCS could not be found on the MDIO bus. To fix this, the Ethernet core
(including the PCS) should be reset after enabling the clocks, prior to
attempting to access the PCS using of_mdio_find_device.

b400c2f4f4 net: axienet: Wait for PhyRstCmplt after core reset
When resetting the device, wait for the PhyRstCmplt bit to be set
in the interrupt status register before continuing initialization, to
ensure that the core is actually ready. When using an external PHY, this
also ensures we do not start trying to access the PHY while it is still
in reset. The PHY reset is initiated by the core reset which is
triggered just above, but remains asserted for 5ms after the core is
reset according to the documentation.

The MgtRdy bit could also be waited for, but unfortunately when using
7-series devices, the bit does not appear to work as documented (it
seems to behave as some sort of link state indication and not just an
indication the transceiver is ready) so it can't really be relied on for
this purpose.

The reason is that the driver isn't prepared to receive two tc filters
with the same cookie. It unconditionally creates a new struct
ocelot_vcap_filter for each tc filter, and it adds all filters with the
same identifier (cookie) to the ocelot_vcap_block.

The problem is here, in ocelot_vcap_filter_del():

	/* Gets index of the filter */
	index = ocelot_vcap_block_get_filter_index(block, filter);
	if (index < 0)
		return index;

	/* Delete filter */
	ocelot_vcap_block_remove_filter(ocelot, block, filter);

	/* Move up all the blocks over the deleted filter */
	for (i = index; i < block->count; i++) {
		struct ocelot_vcap_filter *tmp;

		tmp = ocelot_vcap_block_find_filter_by_index(block, i);
		vcap_entry_set(ocelot, i, tmp);
	}

what will happen is ocelot_vcap_block_get_filter_index() will return the
index (@index) of the first filter found with that cookie. This is _not_
the index of _this_ filter, but the other one with the same cookie,
because ocelot_vcap_filter_equal() gets fooled.

Then later, ocelot_vcap_block_remove_filter() is coded to remove all
filters that are ocelot_vcap_filter_equal() with the passed @filter.
So unexpectedly, both filters get deleted from the list.

Then ocelot_vcap_filter_del() will attempt to move all the other filters
up, again finding them by index (@i). The block count is 2, @index was 0,
so it will attempt to move up filter @i=0 and @i=1. It assigns tmp =
ocelot_vcap_block_find_filter_by_index(block, i), which is now a NULL
pointer because ocelot_vcap_block_remove_filter() has removed more than
one filter.

As far as I can see, this problem has been there since the introduction
of tc offload support, however I cannot test beyond the blamed commit
due to hardware availability. In any case, any fix cannot be backported
that far, due to lots of changes to the code base.

Therefore, let's go for the correct solution, which is to not call
ocelot_vcap_filter_add() and ocelot_vcap_filter_del(), unless the filter
is actually unique and not shared. For the shared filters, we should
just modify the ingress port mask and call ocelot_vcap_filter_replace(),
a function introduced by commit 95706be13b ("net: mscc: ocelot: create
a function that replaces an existing VCAP filter"). This way,
block->rules will only contain filters with unique cookies, by design.

ea93824855 net: apple: bmac: Fix build since dev_addr constification
Since commit adeef3e321 ("net: constify netdev->dev_addr") the bmac

        |                    ^

Fix it by making the modifications to a local macaddr variable and then
passing that to eth_hw_addr_set().

We don't use the existing addr variable because the bitrev8() would
mutate it, but it is already used unreversed later in the function.

33cb0ff30c net: mscc: ocelot: don't let phylink re-enable TX PAUSE on the NPI port
Since commit b39648079d ("net: mscc: ocelot: disable flow control on
NPI interface"), flow control should be disabled on the DSA CPU port
when used in NPI mode.

However, the commit blamed in the Fixes: tag below broke this, because
it allowed felix_phylink_mac_link_up() to overwrite SYS_PAUSE_CFG_PAUSE_ENA
for the DSA CPU port.

This issue became noticeable since the device tree update from commit
8fcea7be57 ("arm64: dts: ls1028a: mark internal links between Felix
and ENETC as capable of flow control").

The solution is to check whether this is the currently configured NPI
port from ocelot_phylink_mac_link_up(), and to not modify the statically
disabled PAUSE frame transmission if it is.

When the port is configured for lossless mode as opposed to tail drop
mode, but the link partner (DSA master) doesn't observe the transmitted
PAUSE frames, the switch termination throughput is much worse, as can be
seen below.

Mask the ECN bits before calling mlx5e_route_lookup_ipv4_get(). The

Pull power management updates from Rafael Wysocki:
 "The most signigicant change here is the addition of a new cpufreq
  'P-state' driver for AMD processors as a better replacement for the
  venerable acpi-cpufreq driver.

  There are also other cpufreq updates (in the core, intel_pstate, ARM
  drivers), PM core updates (mostly related to adding new macros for
  declaring PM operations which should make the lives of driver
  developers somewhat easier), and a bunch of assorted fixes and
  cleanups.

0959a82ab3 net/qla3xxx: Remove useless DMA-32 fallback configuration
As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

So, if dma_set_mask_and_coherent() succeeds, 'pci_using_dac' is known to be
1.

Simplify code and remove some dead code accordingly.

As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

Simplify code and remove some dead code accordingly.

8c6f36d934 bnxt_en: improve firmware timeout messaging
While it has always been possible to infer that an HWRM command was
abandoned due to an unhealthy firmware status by the shortened timeout
reported, this change improves the log messaging to account for this
case explicitly. In the interests of further clarity, the firmware
status is now also reported in these new messages.

v2: Remove inline keyword for hwrm_wait_must_abort() in .c file.

bce9a0b790 bnxt_en: use firmware provided max timeout for messages
Some older devices cannot accommodate the 40 seconds timeout
cap for long running commands (such as NVRAM commands) due to
hardware limitations. Allow these devices to request more time for
these long running commands, but print a warning, since the longer
timeout may cause the hung task watchdog to trigger. In the case of a
firmware update operation, this is preferable to failing outright.

v2: Use bp->hwrm_cmd_max_timeout directly without the constants.

662c9b22f5 bnxt_en: improve VF error messages when PF is unavailable
The current driver design relies on the PF netdev being open in order
to intercept the following HWRM commands from a VF:
    - HWRM_FUNC_VF_CFG
    - HWRM_CFA_L2_FILTER_ALLOC
    - HWRM_PORT_PHY_QCFG (only if FW_CAP_LINK_ADMIN is not supported)

If the PF is closed, then VFs are subjected to rather inscrutable error
messages in response to any configuration requests involving the above
command types. Recent firmware distinguishes this problem case from
other errors by returning HWRM_ERR_CODE_PF_UNAVAILABLE. In most cases,
the appropriate course of action is still to fail, but this can now be
accomplished with the aid of more user informative log messages. For L2
filter allocations that are already asynchronous, an automatic retry
seems more appropriate.

v2: Delete extra newline.

a2d5d6a70f net: ena: Add capabilities field with support for ENI stats capability
This bitmask field indicates what capabilities are supported by the
device.

The capabilities field differs from the 'supported_features' field which
indicates what sub-commands for the set/get feature commands are
supported. The sub-commands are specified in the 'feature_id' field of
the 'ena_admin_set_feat_cmd' struct in the following way:

        struct ena_admin_set_feat_cmd cmd;

        cmd.aq_common_descriptor.opcode = ENA_ADMIN_SET_FEATURE;
        cmd.feat_common.feature_

The 'capabilities' field, on the other hand, specifies different
capabilities of the device. For example, whether the device supports
querying of ENI stats.

Also add an enumerator which contains all the capabilities. The
first added capability macro is for ENI stats feature.

5cad43a52e net: dsa: felix: add port fast age support
Add support for flushing the MAC table on a given port in the ocelot
switch library, and use this functionality in the felix DSA driver.

This operation is needed when a port leaves a bridge to become
standalone, and when the learning is disabled, and when the STP state
changes to a state where no FDB entry should be present.

a14e6b69f3 net: mscc: ocelot: fix incorrect balancing with down LAG ports
Assuming the test setup described here:
https://patchwork.kernel.org/project/netdevbpf/cover/20210205130240.4072854-1-vladimir.oltean@nxp.com/
(swp1 and swp2 are in bond0, and bond0 is in a bridge with swp0)

it can be seen that when swp1 goes down (on either board A or B), then
traffic that should go through that port isn't forwarded anywhere.

A dump of the PGID table shows the following:

PGID_DST[0] = ports 0
PGID_DST[1] = ports 1
PGID_DST[2] = ports 2
PGID_DST[3] = ports 3
PGID_DST[4] = ports 4
PGID_DST[5] = ports 5
PGID_DST[6] = no ports
PGID_AGGR[0] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[1] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[2] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[3] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[4] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[5] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[6] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[7] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[8] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[9] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[10] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[11] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[12] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[13] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[14] = ports 0, 1, 2, 3, 4, 5
PGID_AGGR[15] = ports 0, 1, 2, 3, 4, 5
PGID_SRC[0] = ports 1, 2
PGID_SRC[1] = ports 0
PGID_SRC[2] = ports 0
PGID_SRC[3] = no ports
PGID_SRC[4] = no ports
PGID_SRC[5] = no ports
PGID_SRC[6] = ports 0, 1, 2, 3, 4, 5

Whereas a "good" PGID configuration for that setup should have looked
like this:

PGID_DST[0] = ports 0
PGID_DST[1] = ports 1, 2
PGID_DST[2] = ports 1, 2
PGID_DST[3] = ports 3
PGID_DST[4] = ports 4
PGID_DST[5] = ports 5
PGID_DST[6] = no ports
PGID_AGGR[0] = ports 0, 2, 3, 4, 5
PGID_AGGR[1] = ports 0, 2, 3, 4, 5
PGID_AGGR[2] = ports 0, 2, 3, 4, 5
PGID_AGGR[3] = ports 0, 2, 3, 4, 5
PGID_AGGR[4] = ports 0, 2, 3, 4, 5
PGID_AGGR[5] = ports 0, 2, 3, 4, 5
PGID_AGGR[6] = ports 0, 2, 3, 4, 5
PGID_AGGR[7] = ports 0, 2, 3, 4, 5
PGID_AGGR[8] = ports 0, 2, 3, 4, 5
PGID_AGGR[9] = ports 0, 2, 3, 4, 5
PGID_AGGR[10] = ports 0, 2, 3, 4, 5
PGID_AGGR[11] = ports 0, 2, 3, 4, 5
PGID_AGGR[12] = ports 0, 2, 3, 4, 5
PGID_AGGR[13] = ports 0, 2, 3, 4, 5
PGID_AGGR[14] = ports 0, 2, 3, 4, 5
PGID_AGGR[15] = ports 0, 2, 3, 4, 5
PGID_SRC[0] = ports 1, 2
PGID_SRC[1] = ports 0
PGID_SRC[2] = ports 0
PGID_SRC[3] = no ports
PGID_SRC[4] = no ports
PGID_SRC[5] = no ports
PGID_SRC[6] = ports 0, 1, 2, 3, 4, 5

In other words, in the "bad" configuration, the attempt is to remove the
inactive swp1 from the destination ports via PGID_DST. But when a MAC
table entry is learned, it is learned towards PGID_DST 1, because that
is the logical port id of the LAG itself (it is equal to the lowest
numbered member port). So when swp1 becomes inactive, if we set
PGID_DST[1] to contain just swp1 and not swp2, the packet will not have
any chance to reach the destination via swp2.

The "correct" way to remove swp1 as a destination is via PGID_AGGR
(remove swp1 from the aggregation port groups for all aggregation
codes). This means that PGID_DST[1] and PGID_DST[2] must still contain
both swp1 and swp2. This makes the MAC table still treat packets
destined towards the single-port LAG as "multicast", and the inactive
ports are removed via the aggregation code tables.

The change presented here is a design one: the ocelot_get_bond_mask()
function used to take an "only_active_ports" argument. We don't need
that. The only call site that specifies only_active_ports=true,
ocelot_set_aggr_pgids(), must retrieve the entire bonding mask, because
it must program that into PGID_DST. Additionally, it must also clear the
inactive ports from the bond mask here, which it can't do if bond_mask
just contains the active ports:

	ac = ocelot_read_rix(ocelot, ANA_PGID_PGID, i);
	ac &= ~bond_mask;  <---- here
	/* Don't do division by zero if there was no active
	 * port. Just make all aggregation codes zero.
	 */
	if (num_active_ports)
		ac |= BIT(aggr_idx[i % num_active_ports]);
	ocelot_write_rix(ocelot, ac, ANA_PGID_PGID, i);

So it becomes the responsibility of ocelot_set_aggr_pgids() to take
ocelot_port->lag_tx_active into consideration when populating the
aggr_idx array.

ef39584ddb i40e: Minimize amount of busy-waiting during AQ send
The i40e_asq_send_command will now use a non blocking usleep_range if
possible (non-atomic context), instead of busy-waiting udelay. The
usleep_range function uses hrtimers to provide better performance and
removes the negative impact of busy-waiting in time-critical
environments.

1. Rename i40e_asq_send_command to i40e_asq_send_command_atomic
   and add 5th parameter to inform if called from an atomic context.
   Call inside usleep_range (if non-atomic) or udelay (if atomic).

2. Change i40e_asq_send_command to invoke
   i40e_asq_send_command_atomic(..., false).

3. Change two functions:
    - i40e_aq_set_vsi_uc_promisc_on_vlan
    - i40e_aq_set_vsi_mc_promisc_on_vlan
   to explicitly use i40e_asq_send_command_atomic(..., true)
   instead of i40e_asq_send_command, as they use spinlocks and do some
   work in an atomic context.
   All other calls to i40e_asq_send_command remain unchanged.

 Before this patchset, mlx5 subfunction shared the same IRQs (MSI-X) with
 their peers subfunctions, causing them to use same CPU cores.
 
 In large scale, this is very undesirable, SFs use small number of cpu
 cores and all of them will be packed on the same CPU cores, not
 utilizing all CPU cores in the system.
 
 In this patchset we want to achieve two things.
  a) Spread IRQs used by SFs to all cpu cores
  b) Pack less SFs in the same IRQ, will result in multiple IRQs per core.
 
 In this patchset, we spread SFs over all online cpus available to mlx5
 irqs in Round-Robin manner. e.g.: Whenever a SF is created, pick the next
 CPU core with least number of SF IRQs bound to it, SFs will share IRQs on
 the same core until a certain limit, when such limit is reached, we
 request a new IRQ and add it to that CPU core IRQ pool, when out of IRQs,
 pick any IRQ with least number of SF users.
 
 This enhancement is done in order to achieve a better distribution of
 the SFs over all the available CPUs, which reduces application latency,

4735402173 mlxsw: spectrum: Extend to support Spectrum-4 ASIC
Extend existing driver for Spectrum, Spectrum-2 and Spectrum-3 ASICs
to support Spectrum-4 ASIC as well.

Currently there is no released firmware version for Spectrum-4, so the
driver is not enforcing a minimum version.

852ee4191d mlxsw: spectrum_acl_bloom_filter: Add support for Spectrum-4 calculation
Spectrum-4 will calculate hash function for bloom filter differently
from the existing ASICs.

First, two hash functions will be used to calculate 16 bits result.
The final result will be combination of the two results - 6 bits which
are result of CRC-6 will be used as MSB and 10 bits which are result of
CRC-10 will be used as LSB.

Second, while in Spectrum{2,3}, there is a padding in each chunk, so the
chunks use a sequence of whole bytes, in Spectrum-4 there is no padding,
so each chunk use 20 bytes minus 2 bits, so it is necessary to align the
chunks to be without holes.

Add dedicated 'mlxsw_sp_acl_bf_ops' for Spectrum-4 and add the required
tables for CRC calculations.

All the details are documented as part of the code for future use.

58723d2f77 mlxsw: Add operations structure for bloom filter calculation
Spectrum-4 will calculate hash function for bloom filter differently from
the existing ASICs.

There are two changes:
1. Instead of using one hash function to calculate 16 bits output (CRC-16),
   two functions will be used.
2. The chunks will be built differently, without padding.

As preparation for support of Spectrum-4 bloom filter, add 'ops'
structure to allow handling different calculation for different ASICs.

07ff135958 mlxsw: Introduce flex key elements for Spectrum-4
Spectrum-4 ASIC will support more virtual routers and local ports
compared to the existing ASICs. Therefore, the virtual router and local
port ACL key elements need to be increased.

Introduce new key elements for Spectrum-4 to be aligned with the elements
used already for other Spectrum ASICs.

The key blocks layout is the same for Spectrum-4, so use the existing
code for encode_block() and clear_block(), just create separate blocks.

Note that size of `VIRT_ROUTER_MSB` is 4 bits in Spectrum-4,
therefore declare it using `MLXSW_AFK_ELEMENT_INST_U32()`, in order to
be able to set `.avoid_size_check` to true.
Otherwise, `mlxsw_afk_blocks_check()` will fail and warn.

b6dfff21a1 net/mlx5e: Fix matching on modified inner ip_ecn bits
Tunnel device follows RFC 6040, and during decapsulation inner
ip_ecn might change depending on inner and outer ip_ecn as follows:

 +---------+----------------------------------------+
 |Arriving |         Arriving Outer Header          |
 |   Inner +---------+---------+---------+----------+
 |  Header | Not-ECT | ECT(0)  | ECT(1)  |   CE     |
 +---------+---------+---------+---------+----------+
 | Not-ECT | Not-ECT | Not-ECT | Not-ECT | <drop>   |

 |  ECT(1) |  ECT(1) | ECT(1)  | ECT(1)* |   CE*    |
 |    CE   |   CE    |  CE     | CE      |   CE     |
 +---------+---------+---------+---------+----------+

Cells marked above are changed from original inner packet ip_ecn value.

Tc then matches on the modified inner ip_ecn, but hw offload which
matches the inner ip_ecn value before decap, will fail.

Fix that by mapping all the cases of outer and inner ip_ecn matching,
and only supporting cases where we know inner wouldn't be changed by
decap, or in the outer ip_ecn=CE case, inner ip_ecn didn't matter.

used just a part of the bounce buffer. So syncing overrides the entire
page with bounce buffer that only partially contains real data.

7846665d35 net/mlx5e: Unblock setting vid 0 for VF in case PF isn't eswitch manager
When using libvirt to passthrough VF to VM it will always set the VF vlan
to 0 even if user didn’t request it, this will cause libvirt to fail to
boot in case the PF isn't eswitch owner.

Example of such case is the DPU host PF which isn't eswitch manager, so
any attempt to passthrough VF of it using libvirt will fail.

Fix it by not returning error in case set VF vlan is called with vid 0.

f79a609ea6 net/mlx5: Update log_max_qp value to FW max capability
log_max_qp in driver's default profile #2 was set to 18, but FW actually
supports 17 at the most - a situation that led to the concerning print
when the driver is loaded:
"log_max_qp value in current profile is 18, changing to HCA capabaility
limit (17)"

The expected behavior from mlx5_profile #2 is to match the maximum FW
capability in regards to log_max_qp. Thus, log_max_qp in profile #2 is
initialized to a defined static value (0xff) - which basically means that
when loading this profile, log_max_qp value  will be what the currently
installed FW supports at most.

c1e5da5dd4 ice: improve switchdev's slow-path
In current switchdev implementation, every VF PR is assigned to
individual ring on switchdev ctrl VSI. For slow-path traffic, there
is a mapping VF->ring done in software based on src_vsi value (by
calling ice_eswitch_get_target_netdev function).

With this change, HW solution is introduced which is more
efficient. For each VF, src MAC (VF's MAC) filter will be created,
which forwards packets to the corresponding switchdev ctrl VSI queue
based on src MAC address.

This filter has to be removed and then replayed in case of
resetting one VF. Keep information about this rule in repr->mac_rule,
thanks to that we know which rule has to be removed and replayed
for a given VF.

In case of CORE/GLOBAL all rules are removed
automatically. We have to take care of readding them. This is done
by ice_replay_vsi_adv_rule.

When driver leaves switchdev mode, remove all advanced rules
from switchdev ctrl VSI. This is done by ice_rem_adv_rule_for_vsi.

Flag repr->rule_added is needed because in some cases reset
might be triggered before VF sends request to add MAC.

As the possible failure of the allocation, the devm_ioremap() may return
NULL pointer.
Take tgec_initialization() as an example.
If allocation fails, the params->base_addr will be NULL pointer and will
be assigned to tgec->regs in tgec_config().
Then it will cause the dereference of NULL pointer in set_mac_address(),
which is called by tgec_init().
Therefore, it should be better to add the sanity check after the calling
of the devm_ioremap().

d43e427174 mlxsw: pci: Avoid flow control for EMAD packets
Locally generated packets ingress the device through its CPU port. When
the CPU port is congested and there are not enough credits in its
headroom buffer, packets can be dropped.

While this might be acceptable for data packets that traverse the
network, configuration packets exchanged between the host and the device
(EMADs) should not be subjected to this flow control.

The "sdq_lp" bit in the SDQ (Send Descriptor Queue) context allows the
host to instruct the device to treat packets sent on this queue as
"local processing" and always process them, regardless of the state of
the CPU port's headroom.

Add the definition of this bit and set it for the dedicated SDQ reserved
for the transmission of EMAD packets. This makes the "local processing"
bit in the WQE (Work Queue Element) redundant, so clear it.

command codes. In other words, these not used command codes in VF are also
sepcial command codes theoretically.

So this patch unifes the special command codes and deletes the bool param
is_pf of hclge_comm_send. All the related functions are refactored
according to the new hclge_comm_send function prototype.

9667b81438 net: hns3: create new rss common structure hclge_comm_rss_cfg
Currently PF stores its rss parameters in vport structure. VF stores rss
configurations in hclgevf_rss_cfg structure. Actually hns3 rss parameters
are same beween PF and VF. The two set of rss parameters are redundent and
may add extra bugfix work.

So this patch creates new common rss parameter struct(hclge_comm_rss_cfg)
to unify PF and VF rss configurations.

These new structures will be used to unify rss configurations in PF and VF
rss APIs in next patches.

It is allowed to add both ipv4/ipv6 entries and l2 entries. To add
ipv4/ipv6 entries is not required to use the PGID table while for l2
entries it is required. The PGID table is much smaller than MAC table

sending the requested number of queues to the kernel stack
(due to the asynchronous nature of VF response), in which
case the stack might pick a queue to transmit that is not
enabled and result in Tx hang. Fix this bug by
limiting the total number of queues allocated for VF to

the packet into several buffers when the MTU on the CPU port is
less than the MTU of the switch. The first buffer starts at an
offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the
offset. Thanks to this patch, the user can still connect to the
device in such a situation. For normal configurations, the patch

5055dc0348 net: ena: Fix error handling when calculating max IO queues number
The role of ena_calc_max_io_queue_num() is to return the number
of queues supported by the device, which means the return value
should be >=0.

The function that calls ena_calc_max_io_queue_num(), checks
the return value. If it is 0, it means the device reported
it supports 0 IO queues. This case is considered an error
and is handled by the calling function accordingly.

However the current implementation of ena_calc_max_io_queue_num()
is wrong, since when it detects the device supports 0 IO queues,
it returns -EFAULT.

In such a case the calling function doesn't detect the error,
and therefore doesn't handle it.

This commit changes ena_calc_max_io_queue_num() to return 0
in case the device reported it supports 0 queues, allowing the
calling function to properly handle the error case.

cb3d4f98f0 net: ena: Fix wrong rx request id by resetting device
A wrong request id received from the device is a sign that
something is wrong with it, therefore trigger a device reset.

Also add some debug info to the "Page is NULL" print to make
it easier to debug.

c255a34e02 net: ena: Fix undefined state when tx request id is out of bounds
ena_com_tx_comp_req_id_get() checks the req_id of a received completion,
and if it is out of bounds returns -EINVAL. This is a sign that
something is wrong with the device and it needs to be reset.

The current code does not reset the device in this case, which leaves
the driver in an undefined state, where this completion is not properly
handled.

This commit adds a call to handle_invalid_req_id() in ena_clean_tx_irq()
and ena_clean_xdp_irq() which resets the device to fix the issue.

This commit also removes unnecessary request id checks from
validate_tx_req_id() and validate_xdp_req_id(). This check is unneeded
because it was already performed in ena_com_tx_comp_req_id_get(), which
is called right before these functions.

c95e078069 tehuti: Use dma_set_mask_and_coherent() and simplify code
Use dma_set_mask_and_coherent() instead of unrolling it with some
dma_set_mask()+dma_set_coherent_mask().

Moreover, as stated in [1], dma_set_mask_and_coherent() with a 64-bit mask
will never fail if dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

That said, 'pci_using_dac' can only be 1 after a successful
dma_set_mask_and_coherent().

Simplify code and remove some dead code accordingly.

0a7b6d2218 net: hns3: create new cmdq hardware description structure hclge_comm_hw
Currently PF and VF cmdq APIs use struct hclge(vf)_hw to describe cmdq
hardware information needed by hclge(vf)_cmd_send. There are a little
differences between its child struct hclge_cmq_ring and hclgevf_cmq_ring.
It is redundent to use two sets of structures to support same functions.

So this patch creates new set of common cmdq hardware description
structures(hclge_comm_hw) to unify PF and VF cmdq functions. The struct
hclge_desc is still kept to avoid too many meaningless replacement.

These new structures will be used to unify hclge(vf)_hw structures in PF
and VF cmdq APIs in next patches.

aa36c94853 net/mlx5: Set SMFS as a default steering mode if device supports it
Set SMFS (SW-managed flow steering) as a default steering mode
instead of DMFS (device-managed flow steering)

In SMFS, the driver writes the STEs (Steering Table Entries) directly
to the device's ICM, which allows for a higher rule insertion rate
than through using FW command interface, as it is done in DMFS.

SMFS/DMFS steering modes can be configured through devlink param
'flow_steering_mode'. The possible values are 'smfs' or 'dmfs'.
The desired 'flow_steering_mode' param value should be set before
enabling switchdev mode.

Example:

  # devlink dev param set pci/0000:05:00.0 name flow_steering_mode smfs
  # devlink dev eswitch set pci/0000:05:00.0 mode switchdev

cc2295cd54 net/mlx5: DR, Improve steering for empty or RX/TX-only matchers
Every matcher has RX and TX paths. When a new matcher is created, its RX
and TX start/end anchors are connected to the respective RX and TX anchors
of the previous and next matchers.
This creates a potential performance issue: when a certain rule is added
to a matcher, in many cases it is RX or TX only rule, which may create a
long chain of RX/TX-only paths w/o the actual rules.

This patch aims to handle this issue.

RX and TX matchers are now handled separately: matcher connection in the
matchers chain is split into two separate lists: RX only and TX only.
when a new matcher is created, it is initially created 'detached' - its
RX/TX members are not inserted into the table's matcher list.
When an actual rule is added, only its appropriate RX or TX nic matchers
are then added to the table's nic matchers list and inserted into its
place in the chain of matchers.
I.e., if the rule that is being added is an RX-only rule, only the RX
part of the matcher will be connected to the chain, while TX part of the
matcher remains detached and doesn't prolong the TX chain of the matchers.

Same goes for rule deletion: when the last RX/TX rule of the nic matcher
is destroyed, the nic matcher is removed from its list.

08fac109f7 net/mlx5: DR, Rename list field in matcher struct to list_node

are just list nodes that are stored on the other structs' lists.
Rename the appropriate list field to reflect this distinction.
