net: dsa: add slave VLAN helpers
Add dsa_slave_vlan_add and dsa_slave_vlan_del helpers to handle SWITCHDEV_OBJ_ID_PORT_VLAN switchdev objects. Also copy the switchdev_obj_port_vlan structure on add since we will modify it in future patches. Signed-off-by: Vivien Didelot <vivien.didelot@gmail.com> Signed-off-by: David S.
