Merge branch 'wireless'
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! ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
