Subject: question on random MAC in usbnet

Hi,

I am wondering about the MAC address usbnet is handing
out. In particular why that is a singular address.
Frankly that seems plainly wrong. A MAC is supposed
to be unique, which is just fundamentally incompatible
to using the same MAC for multiple devices, as usbnet
currently potentially does.

Do you think that behavior should be changed to using
a separate random MAC for each device that requires it?

	Regards
		Oliver
