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.
