Merge branch 'mlx5-fixes' into main

Tariq Toukan says:

====================
mlx5 fixes 2024-06-27

This patchset provides fixes from the team to the mlx5 core and EN
drivers.

The first 3 patches by Daniel replace a buggy cap field with a newly
introduced one.

Patch 4 by Chris de-couples ingress ACL creation from a specific flow,
so it's invoked by other flows if needed.

Patch 5 by Jianbo fixes a possible missing cleanup of QoS objects.

Patches 6 and 7 by Leon fixes IPsec stats logic to better reflect the
traffic.

Series generated against:
commit 02ea3120 ("octeontx2-pf: Fix coverity and klockwork issues in octeon PF driver")

V2:
Fixed wrong cited SHA in patch 6.
