I agree. However, in my case, the boards people have assigned MAC addresses
to the chip, they just didn't built the board in such a way as to allow one
to store that MAC address in a permanent way :( And no, I can't use the DT
because the chip is actually on the PCIe bus.
Even with the generation of a random address, it still needs to be copied
into the device, so I would guess that a version of the patch I've sent is
still relevant?
