the tricky thing with embedded hw like this is that all devices might
end up with the same, read-only filesystem, so storing the mac on the FS
and then loading it from there into the HW is... suboptimal.

Would be very nice if busybox had a command that would check the mac
from each IF, and created the random mac from userspace automatically...
