New Revision: 224402
URL: http://svn.freebsd.org/changeset/base/224402

Log:
  MFC r224157:
    Revert r222135 by allowing controller reinitialization.  Due to
    unknown reason Apple UniNorth2 gem(4) device required manual
    interface down/up operation after r222135.  Even though this is not
    correct thing and I don't like to revert it but it would be better
    than breaking gem(4) on PPC.  This should be revisited.
