====================
mlx5-updates-2023-08-07

1) Few cleanups

2) Dynamic completion EQs

The driver creates completion EQs for all vectors directly on driver
load, even if those EQs will not be utilized later on.

To allow more flexibility in managing completion EQs and to reduce the
memory overhead of driver load, this series will adjust completion EQs
creation to be dynamic. Meaning, completion EQs will be created only
when needed.

Patch #1 introduces a counter for tracking the current number of
completion EQs.
Patches #2-6 refactor the existing infrastructure of managing completion
EQs and completion IRQs to be compatible with per-vector
allocation/release requests.
Patches #7-8 modify the CPU-to-IRQ affinity calculation to be resilient
in case the affinity is requested but completion IRQ is not allocated yet.
Patch #9 function rename.
Patch #10 handles the corner case of SF performing an IRQ request when no
SF IRQ pool is found, and no PF IRQ exists for the same vector.
Patch #11 modify driver to use dynamically allocate completion EQs.
