[ 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.
