Subject: [PATCH net-next 11/18] switchdev: remove old netdev_switch_port_bridge_setlink
From: Scott Feldman <sfeldma@...il.com>
New attr-based bridge_setlink can recurse lower devs and recover on err, so
remove old wrapper. Also, restore br_setlink back to original and don't call
into SELF port driver. rtnetlink.c:bridge_setlink already does a call into
port driver for SELF.
