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 but the god-given rule was generally MACs are for life, and the manufacturer prefix was jealously guarded.
As far as I know, locally assigned MACs have always been around, but cloning is more recent. The difference is that LAAs are supposed to set a bit (2 IIRC), whereas cloning does not set that bit. Then again, with the old ARCnet cards, the 8 bit MAC was always manually configured with switches or jumpers. ;-) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
