John W. Linville says: ==================== pull request: wireless-next 2014-07-03 Please pull this first batch of wireless updates intended for the 3.17 stream... For the mac80211 bits, Johannes says: "The biggest thing here is probably Arik's TDLS rework, beyond that we have smaller improvements and features like David's scanning IE thing, Luca's queue work, some CSA work, etc. Also your PID rate control removal, of course." For the iwlwifi bits, Emmanuel says: "I have here a whole bunch of various things. Andy contributes better debug prints for dvm specific flows and a module parameter to completely disable power save for dvm. Andrei is sharing the premises of his work on CSA - more to come. Eran and Liad keep on working on the new devices. I have the regular amount of BT Coex stuff and I continue to work on the firmware error report system adding more debug capabilities. More to come on that subject too." On top of that, there are some cleanups to the new rsi driver, some continuing improvements to the rtl818x drivers, and the usual bundles of updates to ath9k, b43, mwifiex, wil6210, and a few other bits here and there. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
