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.
