  29           This module adds support for wireless adapters based on
  30           Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
  31           of chipsets. For a specific list of supported external
  32           cards, laptops that already ship with these cards and
  33           APs that come with these cards refer to ath9k wiki

  41         bool "Atheros ath9k PCI/PCIe bus support"
  42         default y
  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.
  48
  49 config ATH9K_AHB
  50         bool "Atheros ath9k AHB bus support"
  51         depends on ATH9K
  52         default n
  53         ---help---
  54           This option enables the AHB bus support in ath9k.
  55
  56           Say Y, if you have a SoC with a compatible built-in
  57           wireless MAC. Say N if unsure.
  58

  65           Say Y, if you need access to ath9k's statistics for
  66           interrupts, rate control, etc.
  67
  68           Also required for changing debug message flags at run time.

  81         default n
  82         ---help---
  83           Say N. This should only be enabled on systems undergoing
  84           certification testing and evaluation in a controlled environment.
  85           Enabling this will only enable TX99 support, all other modes of
  86           operation will be disabled.
  87
  88           TX99 support enables Specific Absorption Rate (SAR) testing.
  89           SAR is the unit of measurement for the amount of radio frequency(RF)
  90           absorbed by the body when using a wireless device. The RF exposure
  91           limits used are expressed in the terms of SAR, which is a measure
  92           of the electric and magnetic field strength and power density for
  93           transmitters operating at frequencies from 300 kHz to 100 GHz.
  94           Regulatory bodies around the world require that wireless device
  95           be evaluated to meet the RF exposure limits set forth in the
  96           governmental SAR regulations.
  97
  98 config ATH9K_DFS_CERTIFIED
  99         bool "Atheros DFS support for certified platforms"
 100         depends on ATH9K && CFG80211_CERTIFICATION_ONUS
 101         default n
 102         ---help---
 103           This option enables DFS support for initiating radiation on
 104           ath9k. There is no way to dynamically detect if a card was DFS
 105           certified and as such this is left as a build time option. This
 106           option should only be enabled by system integrators that can
 107           guarantee that all the platforms that their kernel will run on
 108           have obtained appropriate regulatory body certification for a
 109           respective Atheros card by using ath9k on the target shipping
 110           platforms.
 111
 112           This is currently only a placeholder for future DFS support,
 113           as DFS support requires more components that still need to be
 114           developed. At this point enabling this option won't do anything
 115           except increase code size.
 116
 117 config ATH9K_DYNACK
 118         bool "Atheros ath9k ACK timeout estimation algorithm (EXPERIMENTAL)"
 119         depends on ATH9K
 120         default n
 121         ---help---
 122           This option enables ath9k dynamic ACK timeout estimation algorithm
 123           based on ACK frame RX timestamp, TX frame timestamp and frame
 124           duration
 125
 126 config ATH9K_WOW

 128         depends on ATH9K && PM
 129         default n
 130         ---help---
 131           This option enables Wake on Wireless LAN support for certain cards.
 132           Currently, AR9462 is supported.
 133
 134 config ATH9K_RFKILL
 135         bool "Atheros ath9k rfkill support" if EXPERT
 136         depends on ATH9K
 137         depends on RFKILL=y || RFKILL=ATH9K
 138         default y
 139         help
 140           Say Y to have ath9k poll the RF-Kill GPIO every couple of
 141           seconds. Turn off to save power, but enable it if you have
 142           a platform that can toggle the RF-Kill GPIO.
 143
 144 config ATH9K_CHANNEL_CONTEXT
 145        bool "Channel Context support"
 146        depends on ATH9K
 147        default n
 148        ---help---
 149          This option enables channel context support in ath9k, which is needed
 150          for multi-channel concurrency. Enable this if P2P PowerSave support
 151          is required.
 152
 153 config ATH9K_PCOEM
 154         bool "Atheros ath9k support for PC OEM cards" if EXPERT
 155         depends on ATH9K

 176         depends on ATH9K_HTC && DEBUG_FS
 177         ---help---
 178           Say Y, if you need access to ath9k_htc's statistics.
 179
 180 config ATH9K_HWRNG
 181         bool "Random number generator support"
 182         depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K)
 183         default y
 184         ---help---
 185           This option incorporates the ADC register output as a source of
 186           randomness into Linux entropy pool (/dev/urandom and /dev/random)
 187
 188           Say Y, feeds the entropy directly from the WiFi driver to the input
 189           pool.
