Comment 34 for bug 1436940

Yes, steps are:

Get the latest backport from https://www.kernel.org/pub/linux/kernel/projects/backports/2015/07/31/ (the zip/tar file)
Uncompress somewhere
Patch the code with https://github.com/atondwal/linux/commit/22f8a4083883eca3e8a3175315d67d2a04392466
Then do:
make defconfig-ath10k
make
sudo make install

Then, get the latest firmware from https://github.com/kvalo/ath10k-firmware/archive/master.zip
Unzip and copy ath10k folder to /lib/firmware/ath10k
Copy these two files (overwrite what you got before) in /lib/firmware/ath10k/QCA6164/hw2.1:
https://github.com/atondwal/ath10k-firmware/tree/master/ath10k/QCA6164/hw2.1

Create a file named /etc/modprobe.d/ath10k.conf with the following line:

"options ath10k_core skip_otp=y"

Reboot and modprobe ath10k_pci. Do "lshw -C network"; "ip link show" or "rfkill list" to see if you got your card working.
