Enable this if you have a wireless device. 	  For more information refer to documentation on the wireless wiki: 	  https://wireless.wiki.kernel.org/en/developers/Documentation/cfg80211 	  When built as a module it will be called cfg80211. if CFG80211 config NL80211_TESTMODE	bool "nl80211 testmode command"	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"	default n	help	  This option enables some additional warnings that help	  cfg80211 developers and driver developers, but beware that	  they can also 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_CERTIFICATION_ONUS	bool "cfg80211 certification onus"	depends on 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_REQUIRE_SIGNED_REGDB	bool "require regdb signature" if CFG80211_CERTIFICATION_ONUS	default y	select SYSTEM_DATA_VERIFICATION	help	  Require that in addition to the "regulatory.db" file a	  "regulatory.db.p7s" can be loaded with a valid PKCS#7	  signature for the regulatory.db file made by one of the	  keys in the certs/ directory. config CFG80211_USE_KERNEL_REGDB_KEYS	bool "allow regdb keys shipped with the kernel" if CFG80211_CERTIFICATION_ONUS	default y	depends on CFG80211_REQUIRE_SIGNED_REGDB	help	  Allow the regulatory database to be signed by one of the keys for	  which certificates are part of the kernel sources	  (in net/wireless/certs/). 	  This is currently only Seth Forshee's key, who is the regulatory	  database maintainer. config CFG80211_EXTRA_REGDB_KEYDIR	string "additional regdb key directory" if CFG80211_CERTIFICATION_ONUS	depends on CFG80211_REQUIRE_SIGNED_REGDB	help	  If selected, point to a directory with DER-encoded X.509	  certificates like in the kernel sources (net/wireless/certs/)	  that shall be accepted for a signed regulatory database. 	  Note that you need to also select the correct CRYPTO_<hash> modules	  for your certificates, and if cfg80211 is built-in they also must be. 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 where 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"	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.rst. config CFG80211_DEBUGFS	bool "cfg80211 DebugFS entries"	depends on DEBUG_FS	help	  You can enable this if you want debugfs entries for cfg80211. 	  If unsure, say N. config CFG80211_CRDA_SUPPORT	bool "support CRDA" if EXPERT	default y	help	  You should enable this option unless you know for sure you have no	  need for it, for example when using the regulatory database loaded as	  a firmware file. 	  If unsure, say Y. config CFG80211_WEXT	bool "cfg80211 wireless extensions compatibility"	select WEXT_CORE	help	  Enable this option if you need old userspace for wireless	  extensions with cfg80211-based drivers. config CFG80211_KUNIT_TEST	tristate "KUnit tests for cfg80211" if !KUNIT_ALL_TESTS	depends on KUNIT	depends on CFG80211	default KUNIT_ALL_TESTS	help	  Enable this option to test cfg80211 functions with kunit.
