Merge tag 'wireless-drivers-next-for-davem-2015-02-07' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Major changes: iwlwifi: * more work for new devices (4165 / 8260) * cleanups / improvemnts in rate control * fixes for TDLS * major statistics work from Johannes - more to come * improvements for the fw error dump infrastructure * usual amount of small fixes here and there (scan, D0i3 etc...) * add support for beamforming * enable stuck queue detection for iwlmvm * a few fixes for EBS scan * fixes for various failure paths * improvements for TDLS Offchannel wil6210: * performance tuning * some AP features brcm80211: * rework some code in SDIO part of the brcmfmac driver related to suspend/resume that were found doing stress testing * in PCIe part scheduling of worker thread needed to be relaxed * minor fixes and exposing firmware revision information to user-space, ie. ethtool. mwifiex: * enhancements for change virtual interface handling * remove coupling between netdev and FW supported interface combination, now conversion from any type of supported interface types to any other type is possible * DFS support in AP mode ath9k: * fix calibration issues on some boards * Wake-on-WLAN improvements ath10k: * add support for qca6174 hardware * enable RX batching to reduce CPU load Conflicts: drivers/net/wireless/rtlwifi/pci.c Conflict resolution is to get rid of the 'end' label and keep the rest.
