New Revision: 224157
URL: http://svn.freebsd.org/changeset/base/224157

Log:
  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.
