This doesn't look right at all.
Netfilter is for many protocols other than ipv4 (ipv6, bridging, decnet, etc.) so putting it under ipv4 makes not much sense to me.
If anything, probably the "depends on INET" could need correction.

You're right, I'll think about this some more.

Ok, what does this look like?
The only aim of the patch is to put most netfilter options in a dedicated submenu so that one can go tweaking the them right where they've enabled netfilter in the first place. I understand the ordering is a matter of personal opinion (and not much else really), so anybody just tell me if you totally hate this and I'll scrap the idea. :) It just so happens that I've had this cleanup on my TODO since the time I had spawned the "united networking menu."
