See my relpy to Jon Masters mail about there in the future potentially being
other unique identifiers to persistenly name a NIC, given this I'm going to
implement a ifname=eth0:<unique-id> syntax, where for now the unique id will
be a mac, but this way we can easily use other unique-id strings in the future
(much more easily then when we put everything in the ip= syntax)
