txpower is indeed specified in 0.5db steps. removed comment asking for confirmation.

    25 ah_setTxPowerLimit sets the overall (max?) power limit of the device. The integer power limit parameter is specified in 0.5dBm steps. Thus it appears that a value of 20 would represent 10dBm (can someone please confirm?). Also note that ah_setupTxDesc has a txPower parameter, so transmit power can be set on a per-packet basis. It appears that ah_setTxPowerLimit is used to limit the overall device power and the ah_setupTxDesc is used to set the per-ath%d device power limit.
