It does the different trick :) You misunderstood the question. I don't asked how to set the mac address. The question is how to read burned in mac address from user space. ifconfig is not capable doing such a thing. As I can see the drivers read MAC from EEPROM using different ways. Is there any interface to this low level work? WHY: The GNU macchanger has very nice option "--permanent Reset to original, permanent hardware MAC". This is only one thing I haven't ported yet.
