ath10k usb support

Hi all,
I am currently working on implementing high latency support to ath10k,
and as a part of that work I decided to add USB support to the driver.
The implementation is heavily based on the existing ath6kl implementation
with a few tweaks to make it fit into the ath10k code base.
I have also used qcacld2.0 as a reference.
The device I have been using is a usb wifi dongle from Linksys: WUSB6100M
It is based on the QCA9377 chipset.
I have obtained firmware from:
http://www.linksys.com/us/support-article?articleNum=198580
It has been converted into ath10k-firmware using the below options:
API_VER=5
HTT_OP_VERSION="tlv"
WMI_OP_VERSION="tlv"
FW="linksys-wusb6100m/athwlan_AR6320.bin"
OTP="linksys-wusb6100m/otp_AR6320.bin"
FEATURES="ignore-otp-result"
ath10k-fwencoder --create \
--otp=$OTP \
--firmware=$FW \
--set-wmi-op-version=$WMI_OP_VERSION \
--set-htt-op-version=$HTT_OP_VERSION \
--set-fw-api=$API_VER \
--features=$FEATURES
A fork of the ath10k-firmware repo with usb fw file is available here:
https://github.com/erstrom/ath10k-firmware.git
branch: usb
The firmware package from linksys contains board files for different
regions, athwlan.bin, otp.bin and another bin-file named utf.bin.
I have noticed that the utf.bin file seems to be related to some kind of test mode,
so I am unsure if it is needed at all.
Does anyone know what this file could be used for?
A modified ath10k driver with USB support can be found here:
https://github.com/erstrom/linux-ath
branch: ath-201612300921-ath10k-sdio-and-usb
Unfortunately I have run into some problems when configuring the device.
Everything seems to work fine until I issue the HTT RX ring config command.
After that, I start to receive a lot of strange non HTC messages from the device.
I suspect this is some kind of dump-report but I am not sure.
Does anyone recognize the data at the end of this mail (does it make any sense)?
Another problem I have encountered is that I get a non-zero result from the OTP-
execute.
I have tried different OTP exe-params, but I get the same result (3).
Because of this, I added the "ignore-otp-result" parameter to the fw file.
Does anyone know what OTP result 3 mean?
So, in order to summarize:
I don't have a clue what OTP execute result 3 mean (perhaps this is the reason
why the device crashes after the HTT RX ring config message).
Does anyone recognize the below data transmitted from the device after the HTT
RX ring config message has been issued?
All ideas are welcome!
