85 Say N. This should only be enabled on systems undergoing
86 certification testing and evaluation in a controlled environment.
87 Enabling this will only enable TX99 support, all other modes of
88 operation will be disabled.
89
90 TX99 support enables Specific Absorption Rate (SAR) testing.
91 SAR is the unit of measurement for the amount of radio frequency(RF)
92 absorbed by the body when using a wireless device. The RF exposure
93 limits used are expressed in the terms of SAR, which is a measure
94 of the electric and magnetic field strength and power density for
95 transmitters operating at frequencies from 300 kHz to 100 GHz.
96 Regulatory bodies around the world require that wireless device
97 be evaluated to meet the RF exposure limits set forth in the
98 governmental SAR regulations.

103 default n
104 help
105 This option enables DFS support for initiating radiation on
106 ath9k. There is no way to dynamically detect if a card was DFS
107 certified and as such this is left as a build time option. This
108 option should only be enabled by system integrators that can
109 guarantee that all the platforms that their kernel will run on
110 have obtained appropriate regulatory body certification for a
111 respective Atheros card by using ath9k on the target shipping
112 platforms.
113
114 This is currently only a placeholder for future DFS support,
115 as DFS support requires more components that still need to be
116 developed. At this point enabling this option won't do anything
117 except increase code size.
