Underlying firmware will enforce that the maximum tx power will be based on the regulatory requirements. If the user given transmit power is greater than the allowed tx power in the given channel, then the firmware will use the maximum tx power in the same channel. When 0 is sent to the firmware as tx power, it will revert to the default tx power for the station.
