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

John W. Linville says:

====================
This pull request is intended for the 3.8 stream.  It is a bit large
-- I guess Thanksgiving got me off track!  At least the code got to
spend some time in linux-next... :-)

This includes the usual batch of pulls for Bluetooth, NFC, and mac80211
as well as iwlwifi.  Also here is an ath6kl pull, and a new driver
in the rtlwifi family.  The brcmfmac, brcmsmac, ath9k, and mwl8k get
their usual levels of attention, and a handful of other updates tag
along as well.

For more detail on the pulls, please see below...

On Bluetooth, Gustavo says:

"Another set of patches for integration in wireless-next. There are two big set
of changes in it: Andrei Emeltchenko and Mat Martineau added more patches
towards a full Bluetooth High Speed support and Johan Hedberg improve the
single mode support for Bluetooth dongles. Apart from that we have small fixes
and improvements."

...and:

"A few patches to 3.8. The majority of the work here is from Andrei on the High
Speed support. Other than that Johan added support for setting LE advertising
data. The rest are fixes and clean ups and small improvements like support for
a new broadcom hardware."

On mac80211, Johannes says:

"This is for mac80211, for -next (3.8). Plenty of changes, as you can see
below. Some fixes for previous changes like the export.h include, the
beacon listener fix from Ben Greear, etc. Overall, no exciting new
features, though hwsim does gain channel context support for people to
try it out and look at."

...and...:

"This one contains the mac80211-next material. Apart from a few small new
features and cleanups I have two fixes for the channel context code. The
RX_END timestamp support will probably be reworked again as Simon Barber
noted the calculations weren't really valid, but the discussions there
are still going on and it's better than what we had before."

...and:

"Please pull (see below) to get the following changes:
 * a fix & a debug aid in IBSS from Antonio,
 * mesh cleanups from Marco,
 * a few bugfixes for some of my previous patches from Arend and myself,
 * and the big initial VHT support patchset"

And on iwlwifi, Johannes says:

"In addition to the previous four patches that I'm not resending,
we have a number of cleanups, message reduction, firmware error
handling improvements (yes yes... we need to fix them instead)
and various other small things all over."

...and:

"In his quest to try to understand the current iwlwifi problems (like
stuck queues etc.) Emmanuel has first cleaned up the PCIe code, I'm
including his changes in this pull request. Other than that I only have
a small cleanup from Sachin Kamat to remove a duplicate include and a
bugfix to turn off MFP if software crypto is enabled, but this isn't
really interesting as MFP isn't supported right now anyway."

On NFC, Samuel says:

"With this one we have:

- A few HCI improvements in preparation for an upcoming HCI chipset support.
- A pn544 code cleanup after the old driver was removed.
- An LLCP improvement for notifying user space when one peer stops ACKing I
  frames."

On ath6kl, Kalle says:

"Major changes this time are firmware recover support to gracefully
handle if firmware crashes, support for changing regulatory domain and
support for new ar6004 hardware revision 1.4. Otherwise there are just
smaller fixes or cleanups from different people."

Thats about it... :-)  Please let me know if there are problems!

---help---
This option enables the I-Scan method. By default fullmac uses the
new E-Scan method which uses less memory in firmware and gives no
limitation on the number of scan results.
If you say Y here, the Broadcom wireless drivers will register
with ftrace to dump event information into the trace ringbuffer.
Tracing can be enabled at runtime to aid in debugging wireless
issues. This option adds a small amount of overhead when tracing
is disabled. If unsure, say Y to allow developers to better help
you when wireless problems occur.
