This makes sense, but then I think that a cleanup for all the NF_HOOK
calls in the net code to use NFPROTO_* instead of the family would be
interesting for consistency.

BTW, I think that the last chunk of your patch should be a different one
since it fixes NFQUEUE for arptables.

I don't mind about using your patch or mine, both works. Let's fix it,
that's all. Patrick, I leave this up to you.
