config CFG80211 tristate "Improved wireless configuration API" 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. Say N (if you can) unless you know you need wireless extensions for external modules. config NET_WIRELESS_RTNETLINK bool "Wireless Extension API over RtNetlink" depends on WIRELESS_EXT ---help--- Support the Wireless Extension API over the RtNetlink socket in addition to the traditional ioctl interface (selected above). For now, few tools use this facility, but it might grow in the future. The only downside is that it adds 4.5 kB to your kernel.
