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.
