====================
wireless-drivers-next patches for 4.12

Lots of bugfixes as usual but also some new features.

Major changes:

ath10k

* improve firmware download time for QCA6174 and QCA9377, especially
  helps resume time

ath9k_htc

* add support AirTies 1eda:2315 AR9271 device

rt2x00

* add support MT7620

mwifiex

* enable auto deep sleep mode for USB chipsets

brcmfmac

* add support for network namespaces (WIPHY_FLAG_NETNS_OK)
====================
