Bug description:
[Impact]
Impacts all users of ipw2x00-based hardware, for the ipw2200 and ipw2100
drivers: this is fairly common Intel Corporation PRO/Wireless hardware present
in at least quite a few Thinkpad laptops.
[Test Case]
On a system with an Intel PRO/Wireless card:
1) Click the network indicator/applet.
2) Observe the detected signal level.
3) Try to connect to a secured wireless network.
Connection should be successful and ask for the wifi network password
(if it's not already entered)
Alternatively:
1) Run the command 'nmcli dev wifi'.
Signal level should be low (usually visible as simply '0').
[Regression Potential]
This change will modify the detection behavior for the wireless framework to
use for wireless cards. It needs to be properly tested with the affected
devices to make sure the signal level and encryption capabilities are properly
detected; but should also be tested with other devices to make sure signal
levels and encryption capabilities remain properly detected. A possible
regression scenario would be if a device that works with nl80211 (without the
patch) would get detected as needing wext when it is not implemented. This
would likely cause such a device to not be able to see wireless networks and
connect to them.
----
With 3.2.0-29-generic the nm-applet no longer reports the wireless
signal strength. If I reboot into 3.2.0-27-generic this problem does
not occur.
I am using a Toshiba Equium M70-339 laptop, and my wireless card is
listed on the manufacturer's webpage as being an Intel® PRO/Wireless
2200 LAN Mini PCI adaptor integrated in Intel® Centrino™ mobile
technology. I've purged and reinstalled network-manager to no effect.
The only way for me to get the signal strength reported by the nm-
applet is to use an earlier kernel. iwconfig reports the correct
signal quality.

I expect nm-applet to display the signal strength of my WPA2 wireless
AP, but instead no signal is reported. This behaviour is only observed
with the newest kernel.
