Misalignment, MIPS, and ip_hdr(skb)->version

The openwrt tree has long contained a set of patches that correct for
unaligned issues throughout the linux network stack.


unaligned access traps in the packet processing path on certain versions of
the mips architecture is horrifically bad. I had kind of hoped these
patches in some form would have made it upstream by now. (or the
arches that have the issue retired, I think it's mostly just mips24k)
