MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

doc: correct definition of stats per queue feature

Change the documentation to match current usage of this feature
in the NIC table. Moved this sub heading to be after basic
stats because the queue stats reported now are in the same structure.

Although the "Stats per Queue" feature was originally intended
to be related to stats mapping, the overwhelming majority of drivers
report this feature with a different meaning.

Hopefully in later release the per-queue stats limitations
can be fixed, but this requires and API, ABI, and lots of driver
changes.

In switch mode with enabled "repr_matching_en" devarg flag, the match

doc: clarify PCI Virtual Function MTU behavior in mlx5

The mlx5 NIC has a limitation regarding MTU configuration
for PCI Virtual Functions (VFs), setting the MTU on a VF
has no effect on the actual maximum packet size that can
be received. Instead, the maximum receivable packet size
for a VF is determined by the MTU configured on its
associated Physical Function (PF).

DPDK applications using VFs should be prepared to handle
packets up to the size of the PF's configured MTU,
regardless of any MTU settings applied to the VF itself.

net/mlx5: fix counter query loop getting stuck

Counter service thread, responsible for refreshing counter values
stored in host memory, is running an "infinite loop" with the following
logic:

- For each port:
- Refresh port's counter pool - call to __mlx5_hws_cnt_svc().
- Perform aging checks.
- Go to sleep if time left in current cycle.
- Repeat.

__mlx5_hws_cnt_svc() used to perform counter value refresh
implemented the following logic:

1. Store number of counters waiting for reset.
2. Issue ASO WQEs to refresh all counters values.
3. Move counters from reset to reuse list.
Number of moved counters is limited by number stored in step 1 or
step 4.
4. Store number of counters waiting for reset.
5. If number of counters waiting for reset > 0, go to step 2.

Now, if an application constantly creates/destroys flow rules with
counters and even a single counter is added to reset list during step 2,
counter service thread might end up issuing ASO WQEs endlessly,
without going to sleep and respecting the configured cycle time.

This patch fixes that by remove the loop inside __mlx5_hws_cnt_svc().

As a drawback of this fix, the application must allocate enough counters
to accommodate for the cycle time. This number if roughly equal to the
expected counter release rate.

This patch also:

- Ensures that proper counter related error code is returned,
when flow rule create failed due to counter allocation problem.
- Adds debug logging to counter service thread.
- Adds documentation for counter service thread.
