Merge tag 'mlx5-updates-2023-08-16' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux

Saeed Mahameed says:

====================
mlx5-updates-2023-08-16

1) aRFS ethtool stats

Improve aRFS observability by adding new set of counters. Each Rx
ring will have this set of counters listed below.
These counters are exposed through ethtool -S.

1.1) arfs_add: number of times a new rule has been created.
1.2) arfs_request_in: number of times a rule  was requested to move from
   its current Rx ring to a new Rx ring (incremented on the destination
   Rx ring).
1.3) arfs_request_out: number of times a rule  was requested to move out
   from its current Rx ring (incremented on source/current Rx ring).
1.4) arfs_expired: number of times a rule has been expired by the
   kernel and removed from HW.
1.5) arfs_err: number of times a rule creation or modification has
   failed.

2) Supporting inline WQE when possible in SW steering

3) Misc cleanups and fixups to net-next branch

* tag 'mlx5-updates-2023-08-16' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux:
  net/mlx5: Devcom, only use devcom after NULL check in mlx5_devcom_send_event()
