I'd go further and say that we should be able to supply a set of device
properties (such as drvctl -p prints) to the kernel. Let us match a
device by its intrinsic properties (MAC address, serial number, and/or
GUID), and set the unit number according to the device property.
Quentin is right that this *only* helps us to fix the unit number, but I
think that in itself is an important, *feasible* step forward.
