Kalle Valo says:

====================
ath10k:

* enable channel 144 on 5 GHz
* enable Adaptive Noise Immunity (ANI) by default
* add Wake on Wireless LAN (WOW) patterns support
* add basic Tunneled Direct Link Setup (TDLS) support
* add multi-channel support for QCA6174
* enable IBSS RSN support
* enable Bluetooth Coexistance whenever firmware supports it
* add more versatile way to set bitrates used by the firmware

ath9k:

* spectral scan: add support for multiple FFT frames per report

iwlwifi:

* major rework of the scan code (Luca)
* some work on the thermal code (Chaya Rachel)
* some work on the firwmare debugging infrastructure

brcmfmac:

* SDIO suspend and resume fixes
* wiphy band info and changes in regulatory settings
* add support for BCM4324 SDIO and BCM4358 PCIe
* enable support of PCIe devices on router platforms (Hante)
====================
