From 9c2c1c5e7fde82ba79ce36ae56d78dd44b6c4ca8 Mon Sep 17 00:00:00 2001 From: Lama Kayal Date: Sun, 6 Feb 2022 17:42:33 +0200 Subject: [PATCH] net/mlx5e: Separate ethtool_steering from fs.h and make private Create a new fs_ethtool.h header file, where ethtool steering init and cleanup functions are declared in it. Make mlx5e_ethtool_steering struct private and declare at en_fs_ethtool.c.
