    sys/kern             uipc_mbuf.c 
  Log:
  MFC r1.160:
    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.
