====================
wireless-drivers-next patches for 4.20

Second set of patches for 4.20. Heavy refactoring on mt76 continues
and the usual drivers in active development (iwlwifi, qtnfmac, ath10k)
getting new features. And as always, fixes and cleanup all over.

Major changes:

mt76

* more major refactoring to make it easier add new hardware support

* more work on mt76x0e support

* support for getting firmware version via ethtool

* add mt7650 PCI ID

iwlwifi

* HE radiotap cleanup and improvements

* reorder channel optimization for scans

* bump the FW API version

qtnfmac

* fixes for 'iw' output: rates for enabled SGI, 'dump station'

* expose more scan features to host: scan flush and dwell time

* inform cfg80211 when OBSS is not supported by firmware

wlcore

* add support for optional wakeirq

ath10k

* retrieve MAC address from system firmware if provided

* support extended board data download for dual-band QCA9984

* extended per sta tx statistics support via debugfs

* average ack rssi support for data frames

* speed up QCA6174 and QCA9377 firmware download using diag Copy
  Engine

* HTT High Latency mode support needed by SDIO and USB support

* get STA power save state via debugfs

ath9k

* add reset functionality for airtime station debugfs file
