Subject[PATCH net-next v2 3/9] mlxsw: spectrum: Handle PORT_PRE_BRIDGE_FLAGS
Date
In preparation for getting rid of switchdev_port_attr_get(), have mlxsw
check for the bridge flags being set through switchdev_port_attr_set()
when the SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS attribute identifier is
used.
