wireless-drivers-next patches for 4.19

Browse source 
This time a bigger pull request as we have two new Mediatek drivers
 MT76x2u (CONFIG_MT76x2U) and MT76x0U (CONFIG_MT76x0U). Also iwlwifi got
 support for the new IEEE 802.11ax standard, the successor for
 802.11ac. And naturally smaller new features and bugfixes all over.
 
 Major changes:
 
 wcn36xx
 
 * fix WEP in client mode
 
 wil6210
 
 * add support for Talyn-MB (Talyn ver 2.0) device
 
 * add support for enhanced DMA firmware feature
 
 iwlwifi
 
 * implement 802.11ax D2.0
 
 * support for the new 22560 device family
 
 * new PCI IDs for 22000 and 22560
 
 qtnfmac
 
 * implement cfg80211 power management callback
 
 * enable multiple SSIDs scan support
 
 * qtnfmac: implement basic WoWLAN support
 
 mt7601u
 
 * fall back to software encryption for hw unsupported ciphers
 
 * enable 802.11 Management Frame Protection (MFP)
 
 mt76
 
 * support setting RTS threshold
 
 * add USB support
 
 * add support for MT76x2u devices
 
 * add support for MT76x0U devices
 
 mwifiex
 
 * allow user space to set all other IEs except WMM IE
 
 rsi
 
 * add firmware support for AP+BT dual mode
