Initialising the new fibnum field to a known value turns out to
be a GOOD IDEA (TM).
Apparently MOST users set this (e.g. tcp and friends) but there are a few
users that just assume that it is a sensible value but then go on to read it.
These include SCTP, pf and the FLOWTABLE option (and maybe others).
