Atheros QCA6174 (ath10k) not working

[Anthony Jenkins]

I have a Killer 1535 802.11ac wireless card (chipset = Qualcomm Atheros 
QCA6174).  I am using the ath10k/athp driver from git repo 
https://github.com/erikarn/athp.git .  Driver loads, but trying to start 
the interface fails.  What should I be looking at to fix this?

service netif start wlan2:
---------------------------------------------------------------------------

Some notable errors from 'kldload if_athp.ko':

* Driver fails to load firmware file athp_QCA6174_hw3.0/firmware-5.bin; 
it does load file 'athp_QCA6174_hw3.0_firmware-4.bin'.

I assume file 'athp_cal-pci-athp0.bin' is optional calibration data.
