Ah, I hadn't realized how easy it is to spoof a MAC address. When did that happen? How did I miss it? (the last is rhetorical of course) :)
Some network cards have had it forever. Sun Happy-Meal cards for instance. TMK, it doesn't work in general, the hardware has to support it.
Ah, after my time then. Ethernet was bee sting transducers and the very earliest UTP interfaces came out all at 10 Mbps when I was using Suns. I remember there was some special card for HA machines to allow hot standby
I don't think I've ever come across such cards - plain IP take-over has always been enough where I've worked.
but the god-given rule was generally MACs are for life, and the manufacturer prefix was jealously guarded.
With the Sun HMA, you specify the MACs when the driver is loaded :-) If you don't I think you get random addresses.
