config CFG80211 tristate "Improved wireless configuration API" config NL80211 bool "nl80211 new netlink interface support" depends 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_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.
