1config CFG80211 2 tristate "Improved wireless configuration API" 3 4config NL80211 5 bool "nl80211 new netlink interface support" 6 depends on CFG80211 7 default y 8 ---help--- 9 This option turns on the new netlink interface 10 (nl80211) support in cfg80211. 11 12 If =n, drivers using mac80211 will be configured via 13 wireless extension support provided by that subsystem. 14 15 If unsure, say Y. 16 17config WIRELESS_OLD_REGULATORY 18 bool "Old wireless static regulatory definitions" 19 default y 20 ---help--- 21 This option enables the old static regulatory information 22 and uses it within the new framework. This is available 23 temporarily as an option to help prevent immediate issues 24 due to the switch to the new regulatory framework which 25 does require a new userspace application which has the 26 database of regulatory information (CRDA) and another for 27 setting regulatory domains (iw). 28 29 For more information see: 30 31 http://wireless.kernel.org/en/developers/Regulatory/CRDA 32 http://wireless.kernel.org/en/users/Documentation/iw 33 34 It is important to note though that if you *do* have CRDA present 35 and if this option is enabled CRDA *will* be called to update the 36 regulatory domain (for US and JP only). Support for letting the user 37 set the regulatory domain through iw is also supported. This option 38 mainly exists to leave around for a kernel release some old static 39 regulatory domains that were defined and to keep around the old 40 ieee80211_regdom module parameter. This is being phased out and you 41 should stop using them ASAP. 42 43 Say Y unless you have installed a new userspace application. 44 Also say Y if have one currently depending on the ieee80211_regdom 45 module parameter and cannot port it to use the new userspace 46 interfaces. 47 48config WIRELESS_EXT 49 bool "Wireless extensions" 50 default n 51 ---help--- 52 This option enables the legacy wireless extensions 53 (wireless network interface configuration via ioctls.) 54 55 Wireless extensions will be replaced by cfg80211 and 56 will be required only by legacy drivers that implement 57 wireless extension handlers. This option does not 58 affect the wireless-extension backward compatibility 59 code in cfg80211. 60 61 Say N (if you can) unless you know you need wireless 62 extensions for external modules. 63 64config WIRELESS_EXT_SYSFS 65 bool "Wireless extensions sysfs files" 66 default y 67 depends on WIRELESS_EXT && SYSFS 68 help 69 This option enables the deprecated wireless statistics 70 files in /sys/class/net/*/wireless/. The same information 71 is available via the ioctls as well. 72 73 Say Y if you have programs using it, like old versions of 74 hal. 75
