Not every card from the [168c:003e] (rev 32) family works. As I mentioned in my previous post, mine doesn't. Here is its detailed info (lspci -v):

01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
	Subsystem: Samsung Electronics Co Ltd Device 412f
	Flags: bus master, fast devsel, latency 0, IRQ 278
	Memory at f7000000 (64-bit, non-prefetchable) [size=2M]
	Capabilities: [40] Power Management version 3
	Capabilities: [50] MSI: Enable+ Count=8/8 Maskable+ 64bit-
	Capabilities: [70] Express Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [148] Virtual Channel
	Capabilities: [168] Device Serial Number 00-00-00-00-00-00-00-00
	Capabilities: [178] Latency Tolerance Reporting

	Kernel driver in use: ath10k_pci


Notice device ID 412f. According to the .inf file extracted from Windows driver archive (also mentioned in one of my previous messages) there is a whole bunch of different cards with (rev 32).

Only several of them have been tested so far (e.g. 1535 Killer).
