This patch introduce a new driver callback drv_sta_set_txpwr. This API will
copy the transmit power value passed from user space and call the driver
callback to set the tx power for the station.

Atheros NICs use 1/2 dBm increments internally, so maybe pass down mBm to the driver so you don't
loose the granularity? (Other NICs may potentially have even finer control.)
Thanks,
