Well, the problem is that that is racy, because networkd tries to "up"
the device probably even before iw returns.
And iw doesn't support doing this in one step, I have no idea wether
the kernel does.
And this will fail, because there already exists a device with the
same mac address. So my device ends up "failed" from a networkd pov
and I have to restart networkd to get it configured.
