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

First set of new features for 4.20. mt76 driver is going through major
refactoring and that's why there are so many mt76 patches. iwlwifi is
also under heavy development and smaller changes to other drivers.

Also wireless-drivers was merged to fix a conflict between the two trees.

Major changes:

ath10k

* limit available channels via DT ieee80211-freq-limit

wil6210

* add 802.11r Fast Roaming support for AP and station modes

* add support for channel 4

iwlwifi

* new FW API handling

* some improvements in the PCI recovery mechanism

* enable a new scanning feature;

* continued work on HE (mostly radiotap)

* TKIP implementation in new devices

* work continues for new 22560 hardware

mt76

* add support for Alfa AWUS036ACM

* lots of refactoring to make it easier to add new hardware support

* prepare for adding mt76x0e (pci-e variant) support

* add CONFIG_MT76x0E kconfig symbol

brcmfmac

* add support CYW89342 mini-PCIe device

* add 4-way handshake offload detection for FT-802.1X

* enable NL80211_EXT_FEATURE_CQM_RSSI_LIST

* fix for proper support of 160MHz bandwidth

rtl8xxxu

* add rtl8188ctv support
