Kalle Valo says:

====================
wireless-drivers-next patches for 4.15

Mostly fixes this time, but also few new features.

Major changes:

wil6210

* remove ssid debugfs file

rsi

* add WOWLAN support for suspend, hibernate and shutdown states

ath10k

* add support for CCMP-256, GCMP and GCMP-256 ciphers on hardware
  where it's supported (QCA99x0 and QCA4019)
====================
