   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:

  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.
