Ido Schimmel 4f2c6ae5c6 switchdev: Require RTNL mutex to be held when sending FDB notifications ... When switchdev drivers process FDB notifications from the underlying device they resolve the netdev to which the entry points to and notify the bridge using the switchdev notifier. However, since the RTNL mutex is not held there is nothing preventing the netdev from disappearing in the middle, which will cause br_switchdev_event() to dereference a non-existing netdev. Make switchdev drivers hold the lock at the beginning of the notification processing session and release it once it ends, after notifying the bridge. Also, remove switchdev_mutex and fdb_lock, as they are no longer needed when RTNL mutex is held.
