I installed Leap 42.3 on a dell XPS 13 and everything worked fine! However after updating
the wireless doesn't work.. dmesg reports not finding the firmware (ath10k/QCA6174/hw3.0/firmware-5.bin)
I got yet to try downloading and installing the latest firmware rpm (20171009) present in Tumbleweed (not yet in 42.3)..(not sure if this will work...)
would be nice if it where also available in the leap update channel...
