As far as I can tell, the only case currently where the bridge forwards a packet destined for a link-local multicast address is if (p->br->stp_enabled == BR_NO_STP && dest[5] == 0) dest[5] != 0 for an LLDP packet, whose destination address is 01-80-C2-00-00-0E per IEEE 802.1AB-2005. --Ed -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
