I agree this makes sense. Currently I'm forced to do it in a script.
It's especially silly that uml virtual ethernet devices *don't* get
random mac addresses automatically, while tuntap virtual ethernet
devices *do* (in the same kernel tree!).

random_ether_addr() in include/linux/etherdevice.h already takes care of
this.
