It's not clear for my why we should add 3dBm for 2x2 devices
and not for 1x1. 3dBm looks rater like minimal txpower and
hardware transmit at 3dBm + dev->txpower_cur / 2 .
With the change reported txpower value are closer to regulatory
values, but honestly I have no idea what should be reported.
Perhaps also some better comment should be added.
