Subject: question on MAC passthrough and multiple devices in r8152

Hi,

I am looking at the logic the r8152 driver uses to
assign a pass through MAC and I do not understand how
you make sure that it is passed to one device only.
As far as I can see the MAC comes from an ACPI object,
hence the driver will happily read it out and assign
it multiple times. Am I overlooking something?

	Regards
