Subject: [PATCH net-next 5/8] net/mlx5: Add generic getters for other functions caps
Downstream patch requires to get other function GENERAL2 caps while
mlx5_vport_get_other_func_cap() gets only one type of caps (general).
Rename it to represent this and introduce a generic implementation
of mlx5_vport_get_other_func_cap().
