This is quite surprising to me. Maybe it's by accident because the Windows driver is matching too many devices or something?

I don't remember if I mentioned this when you created the r8152 implementation, but this feature could have been easily implemented in userspace given a minimalistic ACPI driver to just read the system MAC. This way it would depend only on the Dell BIOS support, and not on some specific dock. It would even work with third party dongles etc. Having it in userspace would also have made it easier to implement an end user specific policy scheme. There is no need to restrict ourselves to the limited creativeness of Windows developers ;-) Bjørn
