max laire did some of this already... check the pf files now.
there should already be some fib support..

look at teh pre commit diff at:
http://www.freebsd.org/~julian/mrt.diff.

  the pf changes are right at the top.
I will admit that I haven't tested the pf changes, as they are
max's work but as its a "New" feature in freeBSD it can't hurt
any existing setups and I did confirm that the certainly don't break
any other code.
