 15           Say Y, if you want to use the ath9k/ath9k_htc radios together with
 16           Bluetooth modules in the same system.

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

 35 
 36           If you choose to build a module, it'll be called ath9k.

 39         bool "Atheros ath9k PCI/PCIe bus support"
 40         default y
 41         depends on ATH9K && PCI
 42         ---help---
 43           This option enables the PCI bus support in ath9k.
 44 
 45           Say Y, if you have a compatible PCI/PCIe wireless card.
 46 
 47 config ATH9K_AHB
 48         bool "Atheros ath9k AHB bus support"
 49         depends on ATH9K
 50         default n
 51         ---help---
 52           This option enables the AHB bus support in ath9k.
 53 
 54           Say Y, if you have a SoC with a compatible built-in
 55           wireless MAC. Say N if unsure.
 56 
 57 config ATH9K_DEBUGFS
 58         bool "Atheros ath9k debugging"
 59         depends on ATH9K && DEBUG_FS
 60         select MAC80211_DEBUGFS
 61         select RELAY
 62         ---help---
 63           Say Y, if you need access to ath9k's statistics for
 64           interrupts, rate control, etc.
 65 
 66           Also required for changing debug message flags at run time.
 67 
 68 config ATH9K_STATION_STATISTICS
 69         bool "Detailed station statistics"
 70         depends on ATH9K && ATH9K_DEBUGFS && DEBUG_FS

 72         default n
 73         ---help---
 74           This option enables detailed statistics for association stations.
 75 
 76 config ATH9K_DFS_CERTIFIED
 77         bool "Atheros DFS support for certified platforms"
 78         depends on ATH9K && CFG80211_CERTIFICATION_ONUS
 79         default n
 80         ---help---
 81           This option enables DFS support for initiating radiation on
 82           ath9k. There is no way to dynamically detect if a card was DFS
 83           certified and as such this is left as a build time option. This
 84           option should only be enabled by system integrators that can
 85           guarantee that all the platforms that their kernel will run on
 86           have obtained appropriate regulatory body certification for a
 87           respective Atheros card by using ath9k on the target shipping
 88           platforms.
 89 
 90           This is currently only a placeholder for future DFS support,
 91           as DFS support requires more components that still need to be
 92           developed. At this point enabling this option won't do anything
 93           except increase code size.
 94 
 95 config ATH9K_TX99
 96         bool "Atheros ath9k TX99 testing support"
 97         depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS
 98         default n
 99         ---help---
100           Say N. This should only be enabled on systems undergoing
101           certification testing and evaluation in a controlled environment.
102           Enabling this will only enable TX99 support, all other modes of
103           operation will be disabled.
104 
105           TX99 support enables Specific Absorption Rate (SAR) testing.
106           SAR is the unit of measurement for the amount of radio frequency(RF)
107           absorbed by the body when using a wireless device. The RF exposure
108           limits used are expressed in the terms of SAR, which is a measure
109           of the electric and magnetic field strength and power density for
110           transmitters operating at frequencies from 300 kHz to 100 GHz.
111           Regulatory bodies around the world require that wireless device
112           be evaluated to meet the RF exposure limits set forth in the
113           governmental SAR regulations.
114 
115 config ATH9K_WOW
116         bool "Wake on Wireless LAN support (EXPERIMENTAL)"
117         depends on ATH9K && PM
118         default n
119         ---help---
120           This option enables Wake on Wireless LAN support for certain cards.
121           Currently, AR9462 is supported.
122 
123 config ATH9K_LEGACY_RATE_CONTROL
124         bool "Atheros ath9k rate control"
125         depends on ATH9K
126         default n
127         ---help---
128           Say Y, if you want to use the ath9k specific rate control
129           module instead of minstrel_ht. Be warned that there are various
130           issues with the ath9k RC and minstrel is a more robust algorithm.
131           Note that even if this option is selected, "ath9k_rate_control"
132           has to be passed to mac80211 using the module parameter,
133           ieee80211_default_rc_algo.
134 
135 config ATH9K_RFKILL
136         bool "Atheros ath9k rfkill support" if EXPERT
137         depends on ATH9K
138         depends on RFKILL=y || RFKILL=ATH9K
139         default y
140         help
141           Say Y to have ath9k poll the RF-Kill GPIO every couple of
142           seconds. Turn off to save power, but enable it if you have
143           a platform that can toggle the RF-Kill GPIO.
144 
145 config ATH9K_HTC
146        tristate "Atheros HTC based wireless cards support"

158 
159          The built module will be ath9k_htc.
160 
161 config ATH9K_HTC_DEBUGFS
162         bool "Atheros ath9k_htc debugging"
163         depends on ATH9K_HTC && DEBUG_FS
164         ---help---
165           Say Y, if you need access to ath9k_htc's statistics.
