New Revision: 225653
URL: http://svn.freebsd.org/changeset/base/225653

Log:
  Make sure a paused queue gets some frames re-scheduled to the hardware
  once it's unpaused or it'll hang until the next TX'ed frame occurs.
  
  Pointy hat to:	adrian, for removing this call a while back and never
   remembering to restore it.
