The base value used for MT7620 differs from Rt5392 which resulted in

ath.git patches for 4.12. 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

Merge tag 'iwlwifi-next-for-kalle-2017-04-19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next

Another series of patches intended for v4.12.  These are the changes:

 * Heavy work for the A000 device series;
 * Some cleanup patches;
 * A few fixes;
 * Dynamic SAR support;
 * Geographical SAR support;
 * Support a few new PCI device IDs;

When wifi is under scanning/linking/roaming, do not run the reset of the
coex mechanism because these activities are important for wifi, just run
the linking process and return.
