Currently it only sets up qemu user networking +# which limits our ability to be clever. In the long run we should set up a +# tun and a bridge and specify the mac address of the NICs in the emulated +# system and run dnsmasq on it so we test ipv6 and can control which ips which +# nics get and so on -- but this is still better than nothing. + +# TODO: Add a test case for classless static routes. This needs support in +# Qemu first.
