I think they're at least partly separate, since ipfilter has had
stateful packet inspection for longer than ipfw.
Although they no doubt hook into the TCP stack in roughly the same places.

Uh, ipfilter has been in the base sytem for donkey's years
(well, since 4.0 when I started using BSD)
Darren Reed has commit access to our kernel tree,

so patches wouldn't normally be
neccessary if you track STABLE with cvsup.

see the Handbook.

I don't use ipfw, but there's an excellent howto on ipf
