  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.

 100 config ATH9K_DFS_CERTIFIED

 102         depends on ATH9K && CFG80211_CERTIFICATION_ONUS
 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.

 143           seconds. Turn off to save power, but enable it if you have
 144           a platform that can toggle the RF-Kill GPIO.

 151           This option enables channel context support in ath9k, which is needed
 152           for multi-channel concurrency. Enable this if P2P PowerSave support
 153           is required.

 165           This separate driver provides a loader in order to support the
 166           AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have
 167           their initialization data (which contains the real PCI Device ID
 168           that ath9k will need) stored together with the calibration data out
 169           of reach for the ath9k chip.
