It would be nice if at least kernel did not stomp on skb2->h.raw so
ptype callback could cope with situation and report to userspace where
to put checksum. I already discussed it here two or so months ago, and
only solution I was able to find is that VMware's vmnet have to parse
itself network headers to find where to put checksum. Nothing for IPv6
users...
