Surface Go - QCA6174 wifi card not correctly recognized and therefore
not working
Status in linux-firmware package in Ubuntu:
Confirmed
Status in linux-firmware package in Fedora:
Fix Released
Bug description:
Output of dmesg on Surface Go fresh installed Ubuntu 18.10.

There is a board.bin available directly from the vendor
http://www.killernetworking.com/support/K1535_Debian/board.bin
The only thing which is missing is getting this added to
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/boardfiles so
the official board-2.bin. My problem is that I dont know how to read
the board files and modify them because I do not know the encoding
they use.
Also there have been some updates in the upstream linux-firmware repo.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=a87eb5f7bac0f70ade57da57d9126d14eee12336 and
https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0 but
they also do not help to get the wifi card working/recognized.
Any ideas how to get this solved?
Also there is a guide how to port it to Linux
