From 92797e9a480fc1ba267539737419d8c76ad24abd Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 22 Jun 2019 19:38:26 +0800 Subject: [PATCH] net: phylink: ensure consistent phy interface mode [ Upstream commit c678726305b9425454be7c8a7624290b602602fc ] Ensure that we supply the same phy interface mode to mac_link_down() as we did for the corresponding mac_link_up() call. This ensures that MAC drivers that use the phy interface mode in these methods can depend on mac_link_down() always corresponding to a mac_link_up() call for the same interface mode.
