LOL! Well, like I say, I haven't been keeping track of my old MAC addresses
so temporary ones are preferable. And since I haven't been getting IP
address inheritance, I have been ganging my ifconfigs thusly;

pre-up ifconfig eth0 &&  ifconfig eth0 hw ether 00:00:00:00:00:01
up && (etc.)
up ifenslave -e bond0 eth0 eth1

>save the original MAC address in an unused section of the EEPROM.  The
>only unused blocks are at offsets 0x2D-2F (45-47) and 0x34-0x3E
>(52-62).  I suggest changing the diag to check if offset 45-47 is zero,
>and if so saving the original 6 byte station address into those three 16
>bit words.
