John W. Linville says:

====================
Please accept this pull request for the 3.10 stream...

Regarding the mac80211 bits, Johannes says:

"Here I have a bunch of minstrel fixes from Felix, per-interface
multicast filtering from Alex, set_tim debouncing from Ilan,
per-interface debugfs cleanups from Stanislaw, an error return fix from
Wei and a number of small improvements and fixes that I made myself."

And for the iwlwifi bits, Johannes says:

"Andrei changed an instance of kmalloc+memdup to kmemdup, Stanislaw
removed the now unused 5ghz_disable module parameter. I also have a
number of fixes from Ilan, Emmanuel and myself, Emmanuel also continued
working on Bluetooth coexistence."

For the sizeable batch of Bluetooth bits, Gustavo says:

"This is our first batch of patches for 3.10. The biggest changes of this pull
request are from Johan Hedberg, he implemented a HCI request framework to make
life easier when we have to send many HCI commands and a block and wait for
all of the to finish, we were able to fix a few issues in stack with the
introduction of this framework.

Other than that Dean Jenkins did a good work cleaning the RFCOMM code, the
refcnt infrastructure was removed and now we use NULL pointer checks to know
when a object was freed or not. That code was buggy and now it looks a way
better.

The rest of changes are clean ups, fixes and small improvements all over the
Bluetooth subsystem."

Regarding the wl12xx bits, Luca says:

"Some patches intended for 3.10.  Mostly bug fixes and other small
improvements."

On top of that, there are updates to brcmfmac, brcmsmac, b43, ssb and
bcma, as well as mwifiex, rt2x00, and ath9k and a few others.  The most
notable bit is the addition of a new driver in the rtlwifi family.

Please let me know if there are problems!
