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_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_DEFAULT_PS_VALUE int default 1 if CFG80211_DEFAULT_PS default 0 config CFG80211_DEBUGFS bool "cfg80211 DebugFS entries" depends on CFG80211 && DEBUG_FS ---help--- You can enable this if you want to debugfs entries for cfg80211. If unsure, say N. config WIRELESS_OLD_REGULATORY bool "Old wireless static regulatory definitions" default n ---help--- This option enables the old static regulatory information and uses it within the new framework. This option is available for historical reasons and it is advised to leave it off. For details see: http://wireless.kernel.org/en/developers/Regulatory Say N and if you say Y, please tell us why. The default is N. config WIRELESS_EXT bool "Wireless extensions" default y ---help--- This option enables the legacy wireless extensions (wireless network interface configuration via ioctls.) Say Y unless you've upgraded all your userspace to use nl80211 instead of wireless extensions. config WIRELESS_EXT_SYSFS bool "Wireless extensions sysfs files" default y depends on WIRELESS_EXT && SYSFS help This option enables the deprecated wireless statistics files in /sys/class/net/*/wireless/. The same information is available via the ioctls as well. Say Y if you have programs using it, like old versions of hal. config LIB80211 tristate "Common routines for IEEE802.11 drivers" 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. Say Y if you want this built into your kernel. 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. If unsure, say N.
