New Revision: 218962
URL: http://svn.freebsd.org/changeset/base/218962

Log:
  MFC r218710:
    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.
