This patch adds the "set tx_power" command to allow specifying the transmit
power level to the WLAN stack. The transmit power configuration consists of
a mode (automatic, fixed, limited) and the limit mBm value.

No I won't call you stupid. It seems I have forgotten to commit again,
but no worries: The corresponding kernel patch went back to the drawing
