  SVN rev 208201 on 2010-05-17 17:02:42Z by yongari
  
  MFC r207851:
    Implement TSO and TSO over VLAN. Increase number of allowed
    fragmentation of mbuf chain to 32 from 16 because TSO can send 64KB
    sized packet which in turn requires long list of mbuf chain. Due to
    lack of documentation, I'm not sure whether driver have to pull up
    ethernet/IP/TCP header with options to make controller work but
    driver have to parse TCP header to update pseudo TCP checksum
    anyway. The controller expects pseudo TCP checksum computed by
    upper stack and the checksum should follow the MS NDIS
    specification to make TSO work.
