	From looking at the source code for r8169, but it appears that
the r8169 driver only reads the device MAC address at probe time, and
doesn't propogate changes to the MAC out to the device.  That might
explain the "promisc" problem if the device also does MAC filtering.  Am
I missing something in the driver?

	I don't actually have one of these to test with, I'm just
looking at the source and observing that dev_addr is only ever
referenced in the probe function, and that's only to read in the MAC
from the device.
