[net-next,v2,0/6] net/mlx5: Memory optimizations

Message

Shay Drori Dec. 8, 2021, 7 a.m. UTC

This series provides knobs which will enable users to
minimize memory consumption of mlx5 Functions (PF/VF/SF).
mlx5 exposes two new generic devlink params for EQ size
configuration and uses devlink generic param max_macs.

Patches summary:
 - Patches-1-2 Provides I/O EQ size param which enables to save
   up to 128KB.
 - Patches-3-4 Provides event EQ size param which enables to save
   up to 512KB.
 - Patch-5 Clarify max_macs param.
 - Patch-6 Provides max_macs param which enables to save up to 70KB

In total, this series can save up to 700KB per Function.
