patch for networkmanager-0.9.4.0

On IPW2200 wireless cards, networkmanager doesn't show or allow to configure the card for WPA/WPA2. This happens because the ipw2200 driver doesn't report any capabilities or wireless properties using the nl80211 interface to networkmanager.

The Ubuntu people made a patch for networkmanager to fix this issue, it can be found at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/973241 and I'm attaching it. I have tested and it works.
Comment 1 Chí-Thanh Christopher Nguyễn gentoo-dev 2012-07-16 14:12:46 UTC 
If I understand correctly, the NetworkManager patch will help for kernel 3.4 only. Kernel 3.5 will advertise nl80211 support which "probably will not work" and the fallback won't recognize this.
Comment 2 Jonathan Müller 2012-07-16 14:30:57 UTC 
Since kernel 3.5 is not out yet, I can't confirm what you just said, but it is possible. What Networkmanager ought to do is simply to use WEXT with ipw2x00 hardware...
Comment 3 Alexandre Rostovtsev (RETIRED) gentoo-dev 2012-07-16 15:23:58 UTC 
Jonathan, please check whether this upstream patch (which will be in version 0.9.6) fixes the issue for you: http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=50435e1d5deff17233f1de73ee030a5982e9fd05

If it does, we can apply it in 0.9.4.0-r5.
Comment 4 Jonathan Müller 2012-07-16 17:10:35 UTC 
Yes, this patch works!
Comment 5 Alexandre Rostovtsev (RETIRED) gentoo-dev 2012-07-17 05:43:51 UTC 
Should be fixed in 0.9.4.0-r5. Thanks for reporting and testing!
