====================
wireless-drivers-next patches for 4.14

The first wireless-drivers-next pull request for 4.14. I'm submitting
this unusally late in the cycle as my vacation postponed this. But
even if this is late there's not still that much new features, mostly
cleanup or fixes.

Major changes:

ath10k

* preparation for wcn3990 support

iwlwifi

* Reorganization of the code into separate directories continues

qtnfmac

* regulatory support updates

* add get_channel, dump_survey and channel_switch cfg80211 handlers
====================
