0086 operation will be disabled.
0087
0088 TX99 support enables Specific Absorption Rate (SAR) testing.
0089 SAR is the unit of measurement for the amount of radio frequency(RF)
0090 absorbed by the body when using a wireless device. The RF exposure
0091 limits used are expressed in the terms of SAR, which is a measure
0092 of the electric and magnetic field strength and power density for
0093 transmitters operating at frequencies from 300 kHz to 100 GHz.
0094 Regulatory bodies around the world require that wireless device
0095 be evaluated to meet the RF exposure limits set forth in the
0096 governmental SAR regulations.

0102 help
0103 This option enables DFS support for initiating radiation on
0104 ath9k. There is no way to dynamically detect if a card was DFS
0105 certified and as such this is left as a build time option. This
0106 option should only be enabled by system integrators that can
0107 guarantee that all the platforms that their kernel will run on
0108 have obtained appropriate regulatory body certification for a
0109 respective Atheros card by using ath9k on the target shipping
0110 platforms.
0111
0112 This is currently only a placeholder for future DFS support,
0113 as DFS support requires more components that still need to be
0114 developed. At this point enabling this option won't do anything
0115 except increase code size.
