87	  Enabling this will only enable TX99 support, all other modes of

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.

97	  be evaluated to meet the RF exposure limits set forth in the

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.
