  Log:
  When using m_dup(9) to copy more than MHLEN bytes of data, don't create an
  mbuf chain that starts with a cluster containing just MHLEN bytes.  This
  happened because m_dup called m_get or m_getcl depending on the amount of
  data to copy, but then always set the size available in the first mbuf to
  MHLEN.
