But of course we could change this to be defined somwhere instead of calculating it from the real ethernet card's MAC.I think that would be better. It would make it more obvious that the MAC address being used is just made up, and so needs to be carefully chosen.
The specs also say that there are some bits in the first two bytes of the MAC that need to be set when it is a virtual NIC instead of a real card. I have implemented that at work for emulations using tap devices on FreeBSD, but don't have the reference here at home. Bob McConnell N2SPP
