I have replaced the new firmware files to old one. And I build new ath10k_pci.ko ,ath10k_core.ko to get some
The new firmware is still not loaded by ath10k driver .
And I compare the driver codes with 4.7 -rc7 , the codes are almost same.
So the issue should be in firmware scope.
[ 590.486970] ath10k_pci 0000:02:00.0: Hardware name qca6174 hw3.2 version 0x5030000
[ 590.487158] ath10k_pci 0000:02:00.0: Direct firmware load failed with error -2
[ 590.487159] ath10k_pci 0000:02:00.0: Falling back to user helper
keep up the good work

@Perry, could you replace board-2.bin from above link on /lib/firmware/ath10k/QCA6174/hw3.0/ and check if that work ?

I think we can wait till firmware will be updated upstream, however Dell would like to know if what we provide in new RHEL7 release will work on their hardware.
