Right, I think the utility of the feature is clear now. Let me clarify
what I was after - I was wondering which component is responsible for
the address inheritance in Windows or UEFI. Is it also hardcoded into
the realtek driver or is there a way to export the ACPI information to
the network management component?

Also knowing how those OSes handle the new docks which don't have
unique device IDs would obviously be great..
