86 TX99 support enables Specific Absorption Rate (SAR) testing.
87 SAR is the unit of measurement for the amount of radio frequency(RF)
88 absorbed by the body when using a wireless device. The RF exposure
89 limits used are expressed in the terms of SAR, which is a measure
90 of the electric and magnetic field strength and power density for
91 transmitters operating at frequencies from 300 kHz to 100 GHz.

101 This option enables DFS support for initiating radiation on

103 certified and as such this is left as a build time option. This
104 option should only be enabled by system integrators that can
105 guarantee that all the platforms that their kernel will run on
106 have obtained appropriate regulatory body certification for a
107 respective Atheros card by using ath9k on the target shipping
108 platforms.
109
110 This is currently only a placeholder for future DFS support,
