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

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