Ahh, you are right. But you can specify the wiphy name, and then you can use that to query the debugfs to find the MAC addr, and then sync your user-space with that info. It should also be easy enough to specify the MAC address when creating the radio. And, you should be able to create virtual STA, AP, etc, with any specified MAC address, so the MAC of the radio really should not matter much?
