--- Comment #13 from Alan Somers <asomers at FreeBSD.org> ---
FIBs are used to have different routing policies for different kinds of
traffic.  In general, you can't correctly learn which fib you ought to use
based on any feature of a received packet, because different applications can
use different FIBs at the same time.  One application can even use more than
one FIB.

I don't know much about SCTP, but I think that there should be a FIB per
socket.  That's what the socket API currently allows, and it makes intuitive
sense.  Would you ever want to have multiple paths of the same socket get
routed out different interfaces or to different gateways?
