Running Ubuntu 16.04 current of today (4.4.0-15-generic #31-Ubuntu SMP Fri Mar 18 19:08:31 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux) with a Asus z170i pro gaming that comes with the "Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) [168c:003e]" I got wifi-ac working just by adding the board-2.bin file, unload ath10k_pci and ath10k_core, load ath10k_pci.

sudo wget -O /lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin

sudo rmmod ath10k_pci ath10k_core

modprobe ath10k_pci

Monitoring the connection in my router I can see up to 866.7Mbps, though cifs file transfer speed is just about 100Mbps.
