Conflicts: drivers/net/wireless/brcm80211/brcmfmac/dhd_bus.h drivers/net/wireless/rtlwifi/rtl8188ee/phy.h drivers/net/wireless/rtlwifi/rtl8192ce/phy.h drivers/net/wireless/rtlwifi/rtl8192de/phy.h drivers/net/wireless/rtlwifi/rtl8723ae/phy.h Just some minor conflicts between the wireless-next changes and Joe Perches's "extern" removal from function prototypes in header files. John W. Linville says: ==================== Regarding the Bluetooth bits, Gustavo says: "The big work here is from Marcel and Johan. They did a lot of work in the L2CAP, HCI and MGMT layers. The most important ones are the addition of a new MGMT command to enable/disable LE advertisement and the introduction of the HCI user channel to allow applications to get directly and exclusive access to Bluetooth devices." As to the ath10k bits, Kalle says: "Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's just too much to support it. Michal added support for the new firmware interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are minor fixes or cleanups." And also: "Major changes are: * throughput improvements including aligning the RX frames correctly and optimising HTT layer (Michal) * remove qca98xx hw1.0 support (Bartosz) * add support for firmware version 999.999.0.636 (Michal) * firmware htt statistics support (Kalle) * fix WEP in AP and IBSS mode (Marek) * fix a mutex unlock balance in debugfs file (Shafi) And of course there's a lot of smaller fixes and cleanup." For the wl12xx bits, Luca says: "Here are some patches intended for 3.13. Eliad is upstreaming a bunch of patches that have been pending in the internal tree. Mostly bugfixes and other small improvements." Along with that... Arend and friends bring us a batch of brcmfmac updates, Larry Finger offers some rtlwifi refactoring, and Sujith sends the usual batch of ath9k updates. As usual, there are a number of other small updates from a variety of players as well. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
