In other words, what do I tell confused users who see bad checksums
in the tcpdump output over loopback and interfaces capable of
hardware checksums?

That this functionality does not belong in the kernel, as it serves no
real purpose.

OK, I will quote you on that :)

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...
