[Luka Karinja]

Hello. I'm trying to get a M.2 QCA6174 working on my MSI B150Mortar 
motherboard. i did try all the various firmware versions from 
https://github.com/kvalo/ath10k-firmware more or less with the same 
errors as bellow

in dmesg i get: failed to fetch board data for 
bus=pci,vendor=168c,device=003e,subsystem-vendor=0000,subsystem-device=0000 
from ath10k/QCA6174/hw3.0/board-2.bin

when trying to get the device up i get: RTNETLINK answers: Resource 
temporarily unavailable
