====================
wireless-drivers-next patches for 4.10

Major changes:

iwlwifi

* finalize and enable dynamic queue allocation
* use dev_coredumpmsg() to prevent locking the driver
* small fix to pass the AID to the FW
* use FW PS decisions with multi-queue

ath9k

* add device tree bindings
* switch to use mac80211 intermediate software queues to reduce
  latency and fix bufferbloat

wl18xx

* allow scanning in AP mode
====================
