New Revision: 270458
URL: http://svnweb.freebsd.org/changeset/base/270458

  MFC: r268726
  Move the "retry:" label so that the calls to m_pullup() are
  not done after the call to m_defrag(). This fixes a problem
  where m_pullup() would prepend an mbuf to the list created
  by m_defrag() making the chain greater than 32 again.
