The change made in r215906 caused link re-negotiation whenever application joins or leaves a multicast group. If driver is running, it would have established a link so there is no need to start re-negotiation. The re-negotiation broke established link which in turn stopped multicast application working while re-negotiation is in progress. PR: kern/154667 END
