Subject: [PATCH net-next 0/4] net/mlx5: Memory optimizations

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

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

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

Shay Drory (4):
  net/mlx5: Let user configure io_eq_size resource
  net/mlx5: Let user configure event_eq_size resource
  devlink: Clarifies max_macs generic devlink param
  net/mlx5: Let user configure max_macs generic param
