There are all sorts of models used for loading firmware. We don't know
which one is used or what to expect here. We only about the existence
of the device, and will not get any further event for it.

I guess systemd/udev just isn't the right tool to find out about the
actual state of the network interface. The tools which talk to the
interface should deal with that themselves, or a higher-level some
network management service needs to fill the gap here to hook things
up.
