So if the hardware defaults to 00:00:00:00:00:00, what is the
"consistent policy we want to enforce in all drivers"?

A link or hint would be sufficient.

I think the most common strategy for platform drivers these days is

1. use what the hardware provides
2. call of_get_mac_address(dev->of_node, ...)
3. use random_ether_addr

in that order. of_get_mac_address just returns NULL when there
is no device tree or no local-mac-address property, so you can
put it into the driver right away.

Cool, thanks - will do!
