Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next 



John W. Linville says:

====================
Yet one more pull request for wireless updates intended for 3.11...

For the mac80211 bits, Johannes says:

"Here we have a few memory leak fixes related to BSS struct handling
mostly from Ben, including a fix for a more theoretical problem
(associating while a BSS struct times out) from myself, a compilation
warning fix from Arend, mesh fixes from Thomas, tracking the beacon
bitrate (Alex), a bandwidth change event fix (Ilan) and some initial
work for 5/10 MHz channels from Simon."

Regarding the iwlwifi bits, Johannes says:

"Emmanuel removed some unneeded/unsupported module parameters and adds a
Bluetooth 1x1 lookup-table for some upcoming products. From Alex I have
an older patch to add low-power receive support, this depended on a
mac80211 commit that only just came in with the merge from wireless-next
I did. Ilan made beacon timings better, and Eytan added some debug
statements for thermal throttling. I have a few cleanups, a fix for a
long-standing but rare warning, and, arguably the most important patch
here, the firmware API version bump for the 7260/3160 devices."

Also included is a Bluetooth pull -- Gustavo says:

"Here goes a set of patches to 3.11. The biggest work here is from Andre Guedes
on the move of the Discovery to use the new request framework. Other than that
Johan provided a bunch of fixes to the L2CAP code. The rest are just small
fixes and clean ups."

On top of all that, there are a variety of updates and fixes to
brcmfmac, rt2x00, wil6210, ath9k, ath10k, and a few others here and
there.  This also includes a pull of the wireless tree, in order to
prevent some merge conflicts.
