I'll admit being ignorant of higher-level cards, but to my knowledge, MAC
addresses are fixed, like a serial number, on the network card.
Having the ability to pick your MAC address on a local LAN would cause the
same problems as putting your card into promiscuous mode -- you could
intercept traffic intended for other machines. I really don't see this as
Thus, I'm almost certain that the cards these drivers support don't allow
anything like this. I can't promise that for higher-end cards, though.
