    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:

    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
