This patch series allows the BCM GENET, as used on the RPi4, to attach when booted in an ACPI enviroment. The DSDT entry to trigger this is seen below. The second patch in the set retrieves the MAC address from the umac registers rather than carrying it directly in the DSDT. This of course requires the firmware to pre-program it, so we continue to fall back to a random one if it appears to be garbage.
