====================
pull request: wireless-next 2014-09-08

Please pull this batch of updates intended for the 3.18 stream...

For the mac80211 bits, Johannes says:

"Not that much content this time. Some RCU cleanups, crypto
performance improvements, and various patches all over,
rather than listing them one might as well look into the
git log instead."

For the Bluetooth bits, Gustavo says:

"The changes consists of:

        - Coding style fixes to HCI drivers
        - Corrupted ack value fix for the H5 HCI driver
        - A couple of Enhanced L2CAP fixes
        - Conversion of SMP code to use common L2CAP channel API
        - Page scan optimizations when using the kernel-side whitelist
        - Various mac802154 and and ieee802154 6lowpan cleanups
        - One new Atheros USB ID"

For the iwlwifi bits, Emmanuel says:

"We have a new big thing coming up which is called Dynamic Queue
Allocation (or DQA).  This is a completely new way to work with the
Tx queues and it requires major refactoring.  This is being done by
Johannes and Avri.  Besides this, Johannes disables U-APSD by default
because of APs that would disable A-MPDU if the association supports
U-ASPD.  Luca contributed to the power area which he was cleaning
up on the way while working on CSA.  A few more random things here
and there."

For the Atheros bits, Kalle says:

"For ath6kl we had two small fixes and a new SDIO device id.

For ath10k the bigger changes are:

 * support for new firmware version 10.2 (Michal)

 * spectral scan support (Simon, Sven & Mathias)

 * export a firmware crash dump file (Ben & me)

 * cleaning up of pci.c (Michal)

 * print pci id in all messages, which causes most of the churn (Michal)"

Beyond that, we have the usual collection of various updates to ath9k,
b43, mwifiex, and wil6210, as well as a few other bits here and there.

Please let me know if there are problems!
