Even if an all-zero MAC address is not explicitly prohibited it is used in a multiple independent devices. A random address looks more appropriate fore the purpose of generating a UUID. The question is not whether it's good UUID source material. The question, for the purpose of the test, is whether it's valid getnode() output -- which it is for the current logic.

The question is not whether it's good UUID source material. The 
question, for the purpose of the test, is whether it's valid getnode() 
output -- which it is for the current logic.
