 config CFG80211
 	tristate "cfg80211 - wireless configuration API"
 	depends on RFKILL || !RFKILL
 	---help---
 	  cfg80211 is the Linux wireless LAN (802.11) configuration API.
 	  Enable this if you have a wireless device.

 	  For more information refer to documentation on the wireless wiki:

 	  http://wireless.kernel.org/en/developers/Documentation/cfg80211

 	  When built as a module it will be called cfg80211.

 config NL80211_TESTMODE
 	bool "nl80211 testmode command"
 	depends on CFG80211
 	help
 	  The nl80211 testmode command helps implementing things like
 	  factory calibration or validation tools for wireless chips.

 	  Select this option ONLY for kernels that are specifically
 	  built for such purposes.

 	  Debugging tools that are supposed to end up in the hands of
 	  users should better be implemented with debugfs.

 	  Say N.

 config CFG80211_DEVELOPER_WARNINGS
 	bool "enable developer warnings"
 	depends on CFG80211
 	default n
 	help
 	  This option enables some additional warnings that help
 	  cfg80211 developers and driver developers, but that can
 	  trigger due to races with userspace.

 	  For example, when a driver reports that it was disconnected
 	  from the AP, but the user disconnects manually at the same
 	  time, the warning might trigger spuriously due to races.

 	  Say Y only if you are developing cfg80211 or a driver based
 	  on it (or mac80211).


 config CFG80211_REG_DEBUG
 	bool "cfg80211 regulatory debugging"
 	depends on CFG80211
 	default n
 	---help---
 	  You can enable this if you want to debug regulatory changes.
 	  For more information on cfg80211 regulatory refer to the wireless
 	  wiki:

 	  http://wireless.kernel.org/en/developers/Regulatory

 	  If unsure, say N.

 config CFG80211_CERTIFICATION_ONUS
 	bool "cfg80211 certification onus"
 	depends on CFG80211 && EXPERT
 	default n
 	---help---
 	  You should disable this option unless you are both capable
 	  and willing to ensure your system will remain regulatory
 	  compliant with the features available under this option.
 	  Some options may still be under heavy development and
 	  for whatever reason regulatory compliance has not or
 	  cannot yet be verified. Regulatory verification may at
 	  times only be possible until you have the final system
 	  in place.

 	  This option should only be enabled by system integrators
 	  or distributions that have done work necessary to ensure
 	  regulatory certification on the system with the enabled
 	  features. Alternatively you can enable this option if
 	  you are a wireless researcher and are working in a controlled
 	  and approved environment by your local regulatory agency.

 config CFG80211_REG_CELLULAR_HINTS
 	bool "cfg80211 regulatory support for cellular base station hints"
 	depends on CFG80211_CERTIFICATION_ONUS
 	---help---
 	  This option enables support for parsing regulatory hints
 	  from cellular base stations. If enabled and at least one driver
 	  claims support for parsing cellular base station hints the
 	  regulatory core will allow and parse these regulatory hints.
 	  The regulatory core will only apply these regulatory hints on
 	  drivers that support this feature. You should only enable this
 	  feature if you have tested and validated this feature on your
 	  systems.

 config CFG80211_REG_RELAX_NO_IR
 	bool "cfg80211 support for NO_IR relaxation"
 	depends on CFG80211_CERTIFICATION_ONUS
 	---help---
 	 This option enables support for relaxation of the NO_IR flag for
 	 situations that certain regulatory bodies have provided clarifications
 	 on how relaxation can occur. This feature has an inherent dependency on
 	 userspace features which must have been properly tested and as such is
 	 not enabled by default.

 	 A relaxation feature example is allowing the operation of a P2P group
 	 owner (GO) on channels marked with NO_IR if there is an additional BSS
 	 interface which associated to an AP which userspace assumes or confirms
 	 to be an authorized master, i.e., with radar detection support and DFS
 	 capabilities. However, note that in order to not create daisy chain
 	 scenarios, this relaxation is not allowed in cases that the BSS client
 	 is associated to P2P GO and in addition the P2P GO instantiated on
 	 a channel due to this relaxation should not allow connection from
 	 non P2P clients.

 	 The regulatory core will apply these relaxations only for drivers that
 	 support this feature by declaring the appropriate channel flags and
 	 capabilities in their registration flow.

 config CFG80211_DEFAULT_PS
 	bool "enable powersave by default"
 	depends on CFG80211
 	default y
 	help
 	  This option enables powersave mode by default.

 	  If this causes your applications to misbehave you should fix your
 	  applications instead -- they need to register their network
 	  latency requirement, see Documentation/power/pm_qos_interface.txt.

 config CFG80211_DEBUGFS
 	bool "cfg80211 DebugFS entries"
 	depends on CFG80211
 	depends on DEBUG_FS
 	---help---
 	  You can enable this if you want to debugfs entries for cfg80211.

 	  If unsure, say N.

 config CFG80211_INTERNAL_REGDB
 	bool "use statically compiled regulatory rules database" if EXPERT
 	default n
 	depends on CFG80211
 	---help---
 	  This option generates an internal data structure representing
 	  the wireless regulatory rules described in net/wireless/db.txt
 	  and includes code to query that database.  This is an alternative
 	  to using CRDA for defining regulatory rules for the kernel.

 	  Using this option requires some parsing of the db.txt at build time,
 	  the parser will be upkept with the latest wireless-regdb updates but
 	  older wireless-regdb formats will be ignored. The parser may later
 	  be replaced to avoid issues with conflicts on versions of
 	  wireless-regdb.

 	  For details see:

 	  http://wireless.kernel.org/en/developers/Regulatory

 	  Most distributions have a CRDA package.  So if unsure, say N.

 config CFG80211_WEXT_EXPORT
