even if we conceptually separate routing table per interface,
we'd need to look them up together (as one routing table) when
we make outgoing connection. I don't think it very useful to
have per-interface routing table (I don't think there's big win).

BSDs use weak host model, and they do not consider accepting packet
from interface A for interface address on interface B "forwarding".
