So a few years ago I mentioned this at a testing session at I think
Linux Plubmers' and Rusty (CC'ed) commented that he had some netfilter
(or iptables?) simulator code that never made it upstream. However,
now that kselftests are integrated with the kernel this could change.
At least that's my memory of the discussion.

Anyway, I still think its worth trying to submit. Worse case its a
huge pain and we pull it back out?

thanks
