Does it have to be that way? Why can't BR_LEARNING on a BR_PORT_LOCKED cause the learned FDB entries to have BR_FDB_LOCKED, and everything would be ok in that case (the port will not be opened for the learned MAC/VLAN)? > Thus learning is off for locked ports, which of course includes MAB. > > So the 'learning' is based on authorizing MAC,vlan addresses, which > is done by userspace daemons, e.g. hostapd or what could be called > mabd.
