Last time I looked (a couple of years ago), many/most Ethernet adapters
allowed setting a unique MAC address provided that the driver supported it.
One problem we had porting from OS/2 to Win 2K was that the Windows drivers
for the (integrated) adapters we were using didn't allow setting the MAC
address... (we had host connectivity using IEEE 802.2 protocol, with a MAC
to LU mapping scheme.) I suspect the function was there in the OS/2 drivers
because IBM required it to be, as the bigest users of IEEE 802.2 (a
protocol used for SNA connectivity).
