  SVN rev 199325 on 2009-11-16 18:46:33Z by jfv
  
  On a 32 bit kernel the igb driver may cause a page
  fault panic due to a failed bounce page allocation
  during RX mbuf setup. The large demand on bounce pages
  is due to the alignment requirement in the tag, the
  ixgbe driver has demonstrated this to be unnecessary
  and so it is being removed here to fix this problem.
  
  Note that ultimately there needs to be a more elegant
  handling of the failure case here.
