+ 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:
+
+ https://wireless.wiki.kernel.org/en/developers/Documentation/cfg80211
+
+ When built as a module it will be called 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).

+ 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.

+ 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.
