From 66247fbb280c2a699a8621708c52dae6acd2e4bc Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Fri, 3 Apr 2020 11:28:28 +0300 Subject: net/mlx5: Remove Q counter low level helper APIs mlx5 core users are encouraged to use low level API (mlx5_cmd_exec) without the need of helper functions, do this for q counters, remove helper functions and call mlx5_cmd_exec directly from users. This will help reduce the total amount of code and reduction of the mlx5_core symbol table.
