Kalle Valo says:

====================
new driver mt7601u for MediaTek Wi-Fi devices MT7601U

ath10k:

* qca6174 power consumption improvements, enable ASPM etc (Michal)

wil6210:

* support Wi-Fi Simple Configuration in STA mode

iwlwifi:

* a few fixes (re-enablement of interrupts for certain new
  platforms that have special power states)
* Rework completely the RBD allocation model towards new
  multi RX hardware.
* cleanups
* scan reworks continuation (Luca)

mwifiex:

* improve firmware debug functionality

rtlwifi:

* update regulatory database

brcmfmac:

* cleanup and new feature support in PCIe code
* alternative nvram loading for router support
====================

Conflicts:
	drivers/net/wireless/iwlwifi/Kconfig

Trivial conflict in iwlwifi Kconfig, two commits adding
the same two chip numbers to the help text, but order
transposed.
