A few changes:

  When not defining header split do not allocate mbufs,
  this can be a BIG savings in the mbuf memory pool.

  Also keep seperate dma maps for the header and
  payload pieces when doing header split. The basis
  of this code was a patch done a while ago by
  yongari, thank you :)

  A number of white space changes.

MFC: in a few days
