====================
wireless-drivers-next patches for 4.13

Mostly fixes and cleanups, but iwlwifi and rtlwifi had also some new
features.

Major changes:

iwlwifi

* some changes in suspend/resume handling to support new FWs

* Continued work towards the A000 family

* support for a new version of the TX flush FW API

* remove some noise from the kernel logs

rtlwifi

* more bluetooth coexistance improvements
====================
