New Revision: 218710
URL: http://svn.freebsd.org/changeset/base/218710
Log:
Fix a regression introduced in r215906. 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.
