I had a look at some other drivers, and I think we need to be very careful about making setting a random MAC too generic. For example, we might be unlucky and break the possibly_iphdr()-code/assumption in qmi_wwan.c. And there is probably more code/assumptions like that in the network stack. -Kristian
