I've pointed out before that the gross hack of assigning IP address
255.0.0.0/8 to the desired interface should work.  I've just confirmed
that doing that, on RELENG_5_1 and RELENG_4, does result in ping
255.255.255.255 sending ICMP packets out with that dest addr.  I have
not personally tested UDP on FreeBSD, but this hack used to work
on Irix, which at least back then had a bsd-derived network stack,
to enable bootp to work with no kernel mods.
