====================
wireless-drivers-next patches for 4.11

It's nice to see rt2x00 development has becoming active, for example
adding support for a new chip version. Also wcn36xx has been converted
to use the recently merged QCOM_SMD subsystem. Otherwise new features
and fixes it lots of drivers.

Major changes:

iwlwifi

* some more work in preparation for A000 family support
* add support for radiotap timestamps
* some work on our firmware debugging capabilities

wcn36xx

* convert to a proper QCOM_SMD driver (from the platform_driver interface)

ath10k

* VHT160 support
* dump Copy Engine registers during firmware crash
* search board file extension from SMBIOS

wil6210

* add disable_ap_sme module parameter

rt2x00

* support RT3352 with external PA
* support for RT3352 with 20MHz crystal
* add support for RT5350 WiSoC

brcmfmac

* add support for BCM43455 sdio device

rtl8xxxu

* add support for D-Link DWA-131 rev E1, TP-Link TL-WN822N v4 and others
