Rather than else, i think it would be safer to do if (obj->id == SWITCHDEV_OBJ_ID_PORT_MDB) { > + struct switchdev_obj_port_mdb *mdb; > + > + if (!is_multicast_ether_addr(addr.mac)) > + continue; > + > + mdb = SWITCHDEV_OBJ_PORT_MDB(obj); > + mdb->vid = vid; > + ether_addr_copy(mdb->addr, addr.mac); > } It should not happen, but the day it does, we get very confused... > +static int mv88e6xxx_port_mdb_dump(struct dsa_switch *ds, int port, > + struct switchdev_obj_port_mdb *mdb, > + int (*cb)(struct switchdev_obj *obj)) > +{ > + struct mv88e6xxx_chip *chip = ds_to_priv(ds); > + int err; > + > + mutex_lock(&chip->reg_lock); > + err = mv88e6xxx_port_db_dump(chip, port, &mdb->obj, cb); > + mutex_unlock(&chip->reg_lock); > + > + return err; > +} Isn't this identical to mv88e6xxx_port_fdb_dump()? Maybe we should just have one function, and register it twice? Andrew
