25ee03f532 net/bnxt: set flow error after tunnel redirection free
During flow destroy, when bnxt_hwrm_tunnel_redirect_free() fails,
driver is not setting flow error using "rte_flow_error_set".

4171ac66e5 net/bnxt: fix error handling in VNIC prepare
Resources should be freed on error conditions. i.e, VNIC and
VNIC context created in HW and memory allocated in
bnxt_vnic_grp_alloc() should be freed.

Added a new function bnxt_vnic_destroy() to do the cleanup.
This lightweight function can be used in flow destroy/flush
path to avoid duplicate code as well.

52b0e588eb net/bnxt: fix error messages in VNIC prepare
The bnxt_vnic_prep() can fail due to multiple reasons.
But when bnxt_vnic_prep() fails, PMD is not returning

Fix it by moving the "rte_flow_error_set" to bnxt_vnic_prep()

219842b999 net/bnxt: workaround spurious zero stats in Thor
There is a HW bug that can result in certain stats being reported as
zero.
Workaround this by ignoring stats with a value of zero based on the
previously stored snapshot of the same stat.
This bug mainly manifests in the output of func_qstats as FW aggregrates
each ring's stat value to give the per function stat and if one of
them is zero, the per function stat value ends up being lower than the
previous snapshot which shows up as a zero PPS value in testpmd.
Eliminate invocation of func_qstats and aggregate the per-ring stat
values in the driver itself to derive the func_qstats output post
accounting for the spurious zero stat value.

03c8f2fe11 net/bnxt: detect bad opaque in Rx completion
There is a rare hardware bug that can cause a bad opaque value in the RX
or TPA start completion. When this happens, the hardware may have used the
same buffer twice for 2 Rx packets.  In addition, the driver might also
crash later using the bad opaque as an index into the ring.

The Rx opaque value is predictable and is always monotonically increasing.
The workaround is to keep track of the expected next opaque value and
compare it with the one returned by hardware during RX and TPA start
completions. If they miscompare, log it, discard the completion,
schedule a ring reset and move on to the next one.

2ca92f5441 malloc: fix size annotation for NUMA-aware realloc
__rte_alloc_size is mapped to compiler alloc_size attribute.

Quoting gcc documentation:
"""
alloc_size
    The alloc_size attribute is used to tell the compiler that the
    function return value points to memory, where the size is given by
    one or two of the functions parameters. GCC uses this information
    to improve the correctness of __builtin_object_size.

    The function parameter(s) denoting the allocated size are specified
    by one or two integer arguments supplied to the attribute.
    The allocated size is either the value of the single function
    argument specified or the product of the two function arguments
    specified. Argument numbering starts at one.
"""

In rte_realloc_socket case, only 'size' matters.

Note: this has been spotted by Maxime trying to use rte_realloc_socket
and compiling with gcc 11.

ee00af6017 test: remove strict timing requirements some tests
The tests 'alarm_autotest' and 'cycles_autotest' rely on the underlying
system having very accurate and precise timing.  On systems where the
timing isn't as rigid, or the load is particularly high, these tests are
unreliable since the wake latency from the scheduler can be high enough
to miss the timing window.

Remove the timing related tests from the test suites.  These tests now
ensure the add/remove callback infrastructure unit tests, but drop the
waits and reliance on system timing and load.

This avoids FAIL on various testing infrastructures.

But the C register that is used for META item can be 16 or 32 bits
wide depending on kernel and firmware configurations.
Take this into consideration and use the appropriate META width.

23233fd63a net/mlx5: fix loopback for Direct Verbs queue
In the past, all the queues and other hardware objects were created
through Verbs interface. Currently, most of the objects creation are
migrated to Devx interface by default, including queues. Only when
the DV is disabled by device arg or eswitch is enabled, all or some
of the objects are created through Verbs interface.

When using Devx interface to create queues, the kernel driver
behavior is different from the case using Verbs. The Tx loopback
cannot work properly even if the Tx and Rx queues are configured
with loopback attribute. To fix the support self loopback for Tx, a
Verbs dummy queue pair needs to be created to trigger the kernel to
enable the global loopback capability.

This is only required when TIR is created for Rx and loopback is
needed. Only CQ and QP are needed for this case, no WQ(RQ) needs to
be created.

d1ced85a7e net/hns3: fix link speed when VF device is down
When the port is link down state, it is meaningless to display the
port link speed. It should be an undefined state.

b67bdfc8f6 net/hns3: fix DCB reconfiguration
Whether the enable bit of the pfc ("pfc_en") is changed or not is one of
the conditions for reconfiguring the DCB. Currently, pfc_en is not
rolled back when DCB configuration fails. This patch fixes it.

0b92fa1eb0 net/hns3: fix DCB configuration
Currently, the DCB configuration takes effect in the dev_start stage, and
the mapping between TCs and queues are also updated in this stage.
However, the DCB configuration is delivered in the dev_configure stage.

If the configuration fails, it should be intercepted in this stage. If
the configuration succeeds, the user should be able to obtain the
corresponding updated information, such as the mapping between TCs and
queues. So this patch moves DCB configuration to dev_configure.

47ce649fd3 net/hns3: remove meaningless packet buffer rollback
Packet buffer allocation and hardware pause configuration fail normally
when a reset occurs. If the execution fails, rollback of the packet
buffer still fails. So this rollback is meaningless.
