addresses from different subnets on the same interface to work right on
a Linux box; for instance, source address selection is non-deterministic
and you can end up with mismatched source addresses.
However, I do not think this is a big simulation use case and I think
that, more often than not, this will really be indicative of a
I do think we need to support multiple IP addresses per interface but
mainly when we get to IPv6 where that is the norm.
Note: this is somewhat related to bug 85, where we have ifIndexes at
different levels of the system; ip aliaising will definitely break the
alignment of IPv4Interface index to NetDevice index even if we tried to
