Hello Kalle,
Thanks for prompt reply. Frankly, I'm still trying to figure what driver we have really. It's called qcaqcld2.0 but I see references to ath6kl in the various folders relating to the wifi. So that is why I presumed it was based on a ath6kl driver. What exactly is the qcaqcld2.0 driver?
1) Here is the list of files and folders in
/msm8994-la-1-3_amss_oem_standard/LINUX/android/kernel/drivers/net/wireless/ath:
drwxrwxr-x ar5523
drwxrwxr-x ath5k
drwxrwxr-x ath6kl
drwxrwxr-x ath9k
-rw-rw-r-- ath.h
drwxrwxr-x carl9170
-rw-rw-r-- debug.c
-rw-rw-r-- hw.c
-rw-rw-r-- Kconfig
-rw-rw-r-- key.c
-rw-rw-r-- main.c
-rw-rw-r-- Makefile
-rw-rw-r-- regd.c
-rw-rw-r-- regd_common.h
-rw-rw-r-- regd.h
-rw-rw-r-- reg.h
drwxrwxr-x wil6210
As you can see there is no ath10k folder.
2) Here is the list of folders in
/msm8994-la-1-3_amss_oem_standard/LINUX/android/vendor/qcom/proprietary/wlan
drwxrwxr-x ath6kl-utils
drwxrwxr-x cnss-daemon
drwxrwxr-x utils
As you can see it contains an ath6kl-utils folder.
3) When I look in
/msm8994-la-1-3_amss_oem_standard/LINUX/android/vendor/qcom/proprietary/ftm/Android.mk
I see references to BOARD_HAS_ATH_WLAN_AR6320 only, which is useless to us.
4) When I look at athdiag.c, a file inside the qcacld2.0 tools folder, I get the following target info for the register set:
/LINUX/android/vendor/qcom/opensource/wlan/qcacld-2.0/tools/athdiag
static const struct ath_target_info target_info[] = {
{"AR9888_v2", reg_ar9888_v2},
{"AR6320_v1", reg_ar6320_v1},
{"AR6320_v2", reg_ar6320_v2},
{"AR6320_v3", reg_ar6320_v3},
};
5) I will spare you the list of all the other details I have found which raises questions.
I know support for ath10k starts with kernel 4.0 and we have kernel 3.10 but I don't see anything that would tell me that a backport has been applied. And we've been having some issues so that is how I got here.
Regards,
Yan

What makes you think you should use ath6kl with QCA6174? Please provide
details.

ath10k and ath6kl are drivers for different chipsets, you cannot just
choose with one to use. I don't understand why you think you can choose
as you can't.
> Why are we not using ath10k driver?
With QCA6174 you have to use ath10k.
