====================
wireless-drivers-next patches for 4.16

Here are patches which have been accumulating over the holidays and
after the New Year. Business as usual and nothing special really
standing out.

But what's noteworthy here is that Larry Finger is stepping down as
the rtlwifi maintainer. He has been maintaining rtlwifi since it was
applied back in 2010 in commit 0c8173385e54 ("rtl8192ce: Add new
driver") and it has been no easy role trying to juggle between the
vendor, demanding upstream community and users. So big thank you to
Larry for all his efforts!

ath10k

* more preparation work for wcn3990 support

* add memory dump to firmware coredump files

wil6210

* support scheduled scan

* support 40-bit DMA addresses

qtnfmac

* support MAC address based access control

* support for radar detection and Channel Availibility Check (CAC)

mwifiex

* firmware coredump for usb devices

rtlwifi

* Larry Finger steps down as the maintainer and Ping-Ke Shih becomes
  the new maintainer

* add debugfs interfaces to dump register and btcoex status, and also
  write registers and h2c
