TX99 support enables Specific Absorption Rate (SAR) testing. SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations. In the examples below, for more bit rate options see the iw TX bitrate setting documentation: http://wireless.kernel.org/en/users/Documentation/iw#Modifying_transmit_bitrates Example usage: iw phy phy0 interface add moni0 type monitor ip link set dev moni0 up iw dev moni0 set channel 36 HT40+ iw set bitrates mcs-5 4 echo 10 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99_power echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99 Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: Luis R.
