[PATCH net-next v4 0/7] 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 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.
 - Patches-4-5 Provides event EQ size param which enables to save
   up to 512KB.
 - Patch-6 Clarify max_macs param.
 - Patch-7 Provides max_macs param which enables to save up to 70KB

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

changelog:
v3->v4:
- align devlink_param doc of EQ size params to u32.
v2->v3:
- change type of EQ size params to u32 per Jiri suggestion.
- separate ifc changes to new patch
v1->v2:
- convert io_eq_size and event_eq_size from devlink_resources to
  generic devlink_params
