Hi
After this change, on interface reconfig regdomains for both int. and usb radio are no longer 98. instead they are both set to US (int. radio regdomain) while usb should be set to GB. I am not sure if there is an easy way to handle this. Bad thing is that regdomains still intersect for few seconds on usb card insert and during that time int. radio resets it's txpower to max->described in this bug issue: https://bugs.openwrt.org/index.php?do=details&task_id=1745
