Great. Weirdly, we already parse this when we check the routes to determine a
source address, not sure exactly why we never added it to the routes.

Does that also work if the address in RTAX_IFA is on a different interface than
the one configured with RTAX_IFP? (In Martin's case the address is on igb0
while the interface is igb1.)

> FreeBSD has support for multiple routing tables (net.fibs), though there may be some rough edges.

Are these managed via PF_ROUTE interface? Or how does that work/interoperate
exactly?
