Message-ID: <20110603195254.GF2509@tuxdriver.com>
Date: Fri, 3 Jun 2011 15:52:54 -0400
From: "John W. Linville" <linville@...driver.com>

Subject: pull request: wireless-2.6 2011-06-03
Dave,
Here is a batch of fixes intended for 3.0 -- I guess I'll need to
rename my tree eventually... :-)
Included are a libertas fix to ensure proper sequence number assignment
on transmitted frames, an ath9k fix that propogates an earlier fix to a
few more places, a fix for a cfg80211 regression caused by some mesh
code changes, a locking fix for the bluetooth l2cap code, a zd1211rw
regression fix, a collection of small fixes for wl12xx, an iwl4965
fix for a bad temperature check, an a device ID-related fix for iwlagn.
Please let me know if there are problems!
Thanks,
John
