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:
 - Patch-1 Introduce log_max_current_uc_list_wr_supported bit 
 - Patches-2-3 Provides I/O EQ size param which enables to save
   up to 128KB.

   up to 512KB.
