Probably because the ABI between ipfw(8) and it's kernel counterpart has
changed. Since you failed to follow the safe path of upgrade
(mergemaster -p, builworld, buildkernel, installkernel, reboot -s (fall
back in case of problems), mount fs and installkernel, mergemaster),
this sort of things can happen.
Granted, that rather laborious process is usually unnecessary. I,
myself, often use only buildworld, kernel, installworld, mergemaster and
then reboot. And, of course, I'm fully prepared to take Murphy's Revenge
upon my shoulder if these simple steps fail to yield a working system (a
broken kernel, for instance, with a new world incompatible with the
previous kernel).
Short term, cd /usr/src/sbin/ipfw; make depend && make all install ought
to fix it.
