Arjan van de Ven 44a504c405 wireless: fix regression caused by regulatory config option
The default for the regulatory compatibility option is wrong;
if you picked the default you ended up with a non-functional wifi
system (at least I did on Fedora 9 with iwl4965).
I don't think even the October 2008 releases of the various distros
has the new userland so clearly the default is wrong, and also
we can't just go about deleting this in 2.6.29...

Change the default to "y" and also adjust the config text a little to
reflect this.

This patch fixes regression #11859

With thanks to Johannes Berg for the diagnostics

config CFG80211
tristate "Improved wireless configuration API"
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.
config WIRELESS_OLD_REGULATORY
bool "Old wireless static regulatory definitions"
default y
---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.
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.
