Merge tag 'mlx5-updates-2022-11-12' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux

Saeed Mahameed says:

====================
mlx5-updates-2022-11-12

Misc updates to mlx5 driver

1) Support enhanced CQE compression, on ConnectX6-Dx
   Reduce irq rate, cpu utilization and latency.

2) Connection tracking: Optimize the pre_ct table lookup for rules
   installed on chain 0.

3) implement ethtool get_link_ext_stats for PHY down events

4) Expose device vhca_id to debugfs

5) misc cleanups and trivial changes
