Subject: net/mlx5e: SHAMPO: Remove redundant params
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=16142defd304d5a8e591781efe24da498ccfa51f;p=thirdparty%2Flinux.git

net/mlx5e: SHAMPO: Remove redundant params

Two SHAMPO params are static and always the same, remove them from the
global mlx5e_params struct.
