There is another 'problem' the way things work at the moment.

We have over 100 IPPROTO_* defined in in.h. We really do not
want to permit any single one and add it to the switch in

Basically at that point we can have:
1 extension headers (we need to know about them to get to 2 or 3)
2 upper layer protocols we know about and want to do/allow more
   specific filtering (like tcp/udp/..)
3 upper layer protocols ipfw doesn't know about

In case anyone has a good idea what to do with everything in cat 3
feel free to discuss/commit it;)
