  30          Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
  31          of chipsets. For a specific list of supported external

  43        depends on ATH9K && PCI
  44        ---help---
  45          This option enables the PCI bus support in ath9k.
  46
  47          Say Y, if you have a compatible PCI/PCIe wireless card.

  67          interrupts, rate control, etc.
  68
  69          Also required for changing debug message flags at run time.
  70          As well as access to the FFT/spectral data and TX99.

  83        default n
  84        ---help---
  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.

 100config ATH9K_DFS_CERTIFIED
 101        bool "Atheros DFS support for certified platforms"
 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.
 118
 119config ATH9K_DYNACK

 124          This option enables ath9k dynamic ACK timeout estimation algorithm
 125          based on ACK frame RX timestamp, TX frame timestamp and frame
 126          duration

 142          Say Y to have ath9k poll the RF-Kill GPIO every couple of
 143          seconds. Turn off to save power, but enable it if you have
 144          a platform that can toggle the RF-Kill GPIO.

 146config ATH9K_CHANNEL_CONTEXT
 147       bool "Channel Context support"
 148       depends on ATH9K
 149       default n
 150       ---help---
 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.
 154
 155config ATH9K_PCOEM

 190          This option incorporates the ADC register output as a source of
 191          randomness into Linux entropy pool (/dev/urandom and /dev/random)
