[PATCH mlx5-next 1/2] net/mlx5: Rename MLX5_PF page counter type to MLX5_SELF

[Tariq Toukan]

From: Moshe Shemesh <moshe@nvidia.com>

The MLX5_PF enum value in mlx5_func_type is used to track firmware
page allocations for the page manager function itself, which is either
the ECPF on SmartNIC systems or the host PF when there is no ECPF.

Rename it to MLX5_SELF to accurately reflect that this counter tracks
pages allocated by the manager for its own use, regardless of whether
it is a PF or ECPF.

[PATCH mlx5-next 2/2] net/mlx5: Add icm_mng_function_id_mode cap bit

[Tariq Toukan]

From: Moshe Shemesh <moshe@nvidia.com>

Introduce the capability bit icm_mng_function_id_mode to indicate that
the device firmware uses vhca_id instead of function_id as the effective
identifier for the firmware commands MANAGE_PAGES, QUERY_PAGES, and page
request event.
