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. For details see: http://wireless.kernel.org/en/developers/Regulatory Most distributions have a CRDA package. So if unsure, say N. config CFG80211_WEXT bool "cfg80211 wireless extensions compatibility" depends on CFG80211 select WEXT_CORE help Enable this option if you need old userspace for wireless extensions with cfg80211-based drivers. config LIB80211 tristate default n help This options enables a library of common routines used by IEEE802.11 wireless LAN drivers. Drivers should select this themselves if needed. config LIB80211_CRYPT_WEP tristate config LIB80211_CRYPT_CCMP tristate config LIB80211_CRYPT_TKIP tristate config LIB80211_DEBUG bool "lib80211 debugging messages" depends on LIB80211 default n ---help--- You can enable this if you want verbose debugging messages from lib80211.
