Kalle Valo says:
====================
wireless-drivers-next patches for 4.12
Quite a lot of patches for rtlwifi and iwlwifi this time, but changes
also for other active wireless drivers.
Major changes:
ath9k
* add support for Dell Wireless 1601 PCI device
* add debugfs file to manually override noise floor
ath10k
* bump up FW API to 6 for a new QCA6174 firmware branch
wil6210
* support 8 kB RX buffers
iwlwifi
* work to support A000 devices continues
* add support for FW API 30
* add Geographical and Dynamic Specific Absorption Rate (SAR) support
* support a few new PCI device IDs
rtlwifi
* work on adding Bluetooth coexistance support, not finished yet
====================
