config CFG80211 tristate "Improved wireless configuration API" config NL80211 bool "nl80211 new netlink interface support" depends on CFG80211 default y ---help--- This option turns on the new netlink interface (nl80211) support in cfg80211. If =n, drivers using mac80211 will be configured via wireless extension support provided by that subsystem. If unsure, say Y. config WIRELESS_OLD_REGULATORY bool "Old wireless static regulatory definitions" default y ---help--- This option enables the old static regulatory information and uses it within the new framework. This is available temporarily as an option to help prevent immediate issues due to the switch to the new regulatory framework which does require a new userspace application which has the database of regulatory information (CRDA) and another for setting regulatory domains (iw). For more information see: http://wireless.kernel.org/en/developers/Regulatory/CRDA http://wireless.kernel.org/en/users/Documentation/iw It is important to note though that if you *do* have CRDA present and if this option is enabled CRDA *will* be called to update the regulatory domain (for US and JP only). Support for letting the user set the regulatory domain through iw is also supported. This option mainly exists to leave around for a kernel release some old static regulatory domains that were defined and to keep around the old ieee80211_regdom module parameter. This is being phased out and you should stop using them ASAP. Say Y unless you have installed a new userspace application. Also say Y if have one currently depending on the ieee80211_regdom module parameter and cannot port it to use the new userspace interfaces. config WIRELESS_EXT bool "Wireless extensions" default n ---help--- This option enables the legacy wireless extensions (wireless network interface configuration via ioctls.) Wireless extensions will be replaced by cfg80211 and will be required only by legacy drivers that implement wireless extension handlers. This option does not affect the wireless-extension backward compatibility code in cfg80211. Say N (if you can) unless you know you need wireless extensions for external modules. 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
