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

Third set of patches for 4.20. Most notable is finalising ath10k
wcn3990 support, all components should be implemented now.

Major changes:

ath10k

* support NET_DETECT WoWLAN feature

* wcn3990 basic functionality now working after we got QMI support

mt76

* mt76x0e improvements (should be usable now)

* more mt76x0/mt76x2 unification work

brcmsmac

* fix a problem on AP mode with clients using power save mode

iwlwifi

* support for a new scan type: fast balance
====================
