config CFG80211
tristate "Improved wireless configuration API"
config CFG80211_REG_DEBUG
bool "cfg80211 regulatory debugging"
depends on CFG80211
default n
---help---
You can enable this if you want to debug regulatory changes.
If unsure, say N.
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.
cfg80211: Add new wireless regulatory infrastructure This adds the new wireless regulatory infrastructure. The main motiviation behind this was to centralize regulatory code as each driver was implementing their own regulatory solution, and to replace the initial centralized code we have where: * only 3 regulatory domains are supported: US, JP and EU * regulatory domains can only be changed through module parameter * all rules were built statically in the kernel We now have support for regulatory domains for many countries and regulatory domains are now queried through a userspace agent through udev allowing distributions to update regulatory rules without updating the kernel. Each driver can regulatory_hint() a regulatory domain based on either their EEPROM mapped regulatory domain value to a respective ISO/IEC 3166-1 country code or pass an internally built regulatory domain. We also add support to let the user set the regulatory domain through userspace in case of faulty EEPROMs to further help compliance. Support for world roaming will be added soon for cards capable of this. For more information see: http://wireless.kernel.org/en/developers/Regulatory/CRDA For now we leave an option to enable the old module parameter, ieee80211_regdom, and to build the 3 old regdomains statically (US, JP and EU). This option is CONFIG_WIRELESS_OLD_REGULATORY. These old static definitions and the module parameter is being scheduled for removal for 2.6.29. Note that if you use this you won't make use of a world regulatory domain as its pointless. If you leave this option enabled and if CRDA is present and you use US or JP we will try to ask CRDA to update us a regulatory domain for us. Signed-off-by: Luis R.

---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.
Note: You will need CRDA if you want 802.11d support
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.
