As FYI. It seems that in the past 4 days or so that 'make defconfig' for Netgear R7800 has been changed to use the ath10k-ct driver by default, which makes wireless perform like utter garbage in my trunk builds (at least on my R7800). Not sure if this was an intended change or not.
Changing config back to use the normal ath10k driver restores the usual stellar performance.
I find this change quite strange as you're more or less required to provide test results and documentation on why change X should be made which isn't stated anywhere as far as I can tell. I guess it depends on who's committing...
(Moved to the For Developers section.)
Same here for my Zyxel NBG6817. Less performance and it feels like unstable. If I look into Luci I can see Signal/Noise is flipping arround like hell compared to stock driver. For me it looks like that there a kind of powermanagement activated. I don't know. Anyway ...
I have reverted this change. You can do this for your device too.

Maybe it's usefull. I think it would be a good idea to announce such (imo) far-reaching changes. Especially if developers want to collect informations ...
I have to mention that if I did this build I simply made a defconfig. I was not aware of this change. I realized this first after 1st reboot.
