Assume I have two computers hooked up via Ethernet and via Firewire
(if_fwe). Will this commit allow me to place all four IP addresses of
the interfaces into the same subnet and have FreeBSD re-route the
packets through Firewire if the Ethernet link goes down (or vice versa)?

Or do I need to go CARP for this to work?
