x86 architectures can handle unaligned accesses in hardware, and it has
been shown that unaligned DMA accesses can be expensive on Nehalem
architectures.  As such we should overwrite NET_IP_ALIGN to resolve
this issue.

Can I get an x86'er ACK on this?  I can merge it in via net-next-2.6
which is probably most convenient for people who want to see the
networking performance effects of this change.
