I have a DELL XPS 15 laptop with a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter. From time to time, I receive crashes in the driver like the following. It is getting annoying. I tried to upgrade the firmware to the latest one provided here:

https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174  


Here is the driver details:
