From: Jianbo Liu Date: Fri, 2 Mar 2018 02:09:08 +0000 (+0000) Subject: net/mlx5e: Don't override vport admin link state in switchdev mode X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=baab1f0c4885854cefec9f2b0da9abc912333a25;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net/mlx5e: Don't override vport admin link state in switchdev mode The vport admin original link state will be re-applied after returning back to legacy mode, it is not right to change the admin link state value when in switchdev mode. Use direct vport commands to alter logical vport state in netdev representor open/close flows rather than the administrative eswitch API.
