Lo! Splitting this thread to focus on a issue that has nothing to do with the regression in 4.14 I reported:

But while at it: If you have a minute, could you please explain to me how to properly set up the wifi firmware files for my Dell XPS13 (9360)? The reasons why I'm asking: Sending data via wifi is really slow on my laptop (scp copies only get 2 to 5 MByte/s on networks that are known to be a lot faster). I wonder if the firmware files or the calibration data is part of the reason wifi Tx is slow. The machine is normally shipped with a slightly enhanced Ubuntu 16.04. That among others contains a package with the machine specific files board.bin and board-2.bin that replace the files normally installed in /lib/firmware/ath10k/QCA6174/hw3.0/ Are those machine specific files crucial to have or are the one from the linux-firmware repo good enoguh? I'm using Fedora and could copy the ones from Ubuntu over, but obviously they will get overwritten every time Fedora ships a new linux-firmware package – IOW: every few weeks :-/ Side note: You find a lot of reports about slow wifi is you search the net with terms like "9360 wifi slow linux". Ubuntu fixed that a few months ago with this patch: http://kernel.ubuntu.com/git/ubuntu/ubuntu-xenial.git/commit/?id=9690f19f07fee2acb2b04ea5eaa5db184ee175d5 Some bugs about this: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1692836 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1670041 But from what I gathered by searching the net and asking on #ath10k I got the impression that patch is a massive ugly hack and no way acceptable upstream. Is that correct? If yes: is there maybe a proper fix out there somewhere?
