28	  This module adds support for wireless adapters based on
29	  Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
30	  of chipsets. For a specific list of supported external

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

40	bool "Atheros ath9k PCI/PCIe bus support"
41	default y
42	depends on ATH9K && PCI

78	depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS
79	default n
80	help
81	  Say N. This should only be enabled on systems undergoing
82	  certification testing and evaluation in a controlled environment.
83	  Enabling this will only enable TX99 support, all other modes of
84	  operation will be disabled.
85
86	  TX99 support enables Specific Absorption Rate (SAR) testing.
87	  SAR is the unit of measurement for the amount of radio frequency(RF)
88	  absorbed by the body when using a wireless device. The RF exposure
89	  limits used are expressed in the terms of SAR, which is a measure
90	  of the electric and magnetic field strength and power density for
91	  transmitters operating at frequencies from 300 kHz to 100 GHz.
92	  Regulatory bodies around the world require that wireless device
93	  be evaluated to meet the RF exposure limits set forth in the
94	  governmental SAR regulations.
95
96config ATH9K_DFS_CERTIFIED
97	bool "Atheros DFS support for certified platforms"
98	depends on ATH9K && CFG80211_CERTIFICATION_ONUS
99	default n
100	help
101	  This option enables DFS support for initiating radiation on
102	  ath9k. There is no way to dynamically detect if a card was DFS
103	  certified and as such this is left as a build time option. This
104	  option should only be enabled by system integrators that can
105	  guarantee that all the platforms that their kernel will run on
106	  have obtained appropriate regulatory body certification for a
107	  respective Atheros card by using ath9k on the target shipping
108	  platforms.
109
110	  This is currently only a placeholder for future DFS support,
111	  as DFS support requires more components that still need to be
112	  developed. At this point enabling this option won't do anything
113	  except increase code size.
114
115config ATH9K_DYNACK

126	depends on ATH9K && PM
127	default n
128	help
129	  This option enables Wake on Wireless LAN support for certain cards.
130	  Currently, AR9462 is supported.

136	default y
137	help
138	  Say Y to have ath9k poll the RF-Kill GPIO every couple of
139	  seconds. Turn off to save power, but enable it if you have
140	  a platform that can toggle the RF-Kill GPIO.
141
142config ATH9K_CHANNEL_CONTEXT
143	bool "Channel Context support"
144	depends on ATH9K
145	default n
146	help
147	  This option enables channel context support in ath9k, which is needed
148	  for multi-channel concurrency. Enable this if P2P PowerSave support
149	  is required.
150

160	help
161	  This separate driver provides a loader in order to support the
162	  AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have
163	  their initialization data (which contains the real PCI Device ID
164	  that ath9k will need) stored together with the calibration data out
165	  of reach for the ath9k chip.
166
167	  These devices are usually various network appliances, routers or
168	  access Points and such.
169
170	  If unsure say N.
