So I've copied deviskec post and fixed the recent breakage due to the merge of ominous 'ath-next' branche which broke ath10k.

1. Download the firmware binaries

https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/board.bin
https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/firmware-4.bin

and put them in the /lib/firmware/ath10k/QCA6174/hw2.1/ folder (create the folder if it doesnt exist)

Commands:

sudo mkdir -p /lib/firmware/ath10k/QCA6174/hw2.1/
sudo wget https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/board.bin -O /lib/firmware/ath10k/QCA6174/hw2.1/board.bin
sudo wget https://github.com/sumdog/ath10k-firmware/raw/5faf5bb7c7413f9bb332693179de54cca6fff58e/ath10k/QCA6174/hw2.1/firmware-4.bin -O /lib/firmware/ath10k/QCA6174/hw2.1/firmware-4.bin

2. Install dependencies to be able to compile the kernel with:

sudo apt-get install libncurses5-dev gcc make git exuberant-ctags

3. Download kvalo's kernel tree from:

https://mega.nz/#!9A8UTLLL!7CDjBmSwNTudX9Upz6yRk7BabKE4w2J8_GCwLrKh27c
NB: I could find a link to the correct, RC7 zip. Perhaps it's already fixed in the master branch, otherwise use my uploaded mega link

and extract it to a folder (no need to apply any patch, it's been merged already).

NB: I couldn't get this to work with the command line unzip, so use the gui extraction tool.

5. Navigate to the extracted folder and run the following commands:

cp /boot/config-`uname -r`* .config
make olddefconfig
make -j`cat /proc/cpuinfo | grep -c processor`

(this automatically uses the best amount of jobs for your CPU)
(wait a while for it to compile, and after run)

sudo make INSTALL_MOD_STRIP=1 modules_install install
(stripping symbols makes the initrd the regular ~30MB instead of 238MB)

6. Create config file with:

echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k.conf

7. Reboot using your new kernel 4.x.x-wl-ath
(will be automatically selected)

8. Run ifconfig

Works perfectly without any drops. Would be nice that people who succeed comment on the following PR:

https://github.com/kvalo/ath10k-firmware/pull/2

so we can get this merged to mainstream kernel.
