From f123f2fbedc7c2723ceb050cd88c2ea1d6a8be32 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Fri, 27 Jan 2017 15:29:41 -0500 Subject: net: dsa: pass bridge device when a port leaves Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already unbridged, so reflect this by assigning the port's bridge_dev pointer to NULL before calling the port_bridge_leave DSA driver operation. Now that the bridge_dev pointer is exposed to the drivers, reflecting the current state of the DSA switch fabric is necessary for the drivers to adjust their port based VLANs correctly. Pass the bridge device pointer to the port_bridge_leave operation so that drivers have all information to re-program their chips properly, and do not need to cache it anymore.
