Sorry for the delay in my answer. But like Greg said, use of a newer
kernel is the best option. I don't have the bandwith to maintain ath[1]
drivers in stable releases, but I do try to make sure bugfixes have a
Fixes tag when approriate and I do add cc stable whenever people ask me
to. That's about it from stable releases point of view, my focus is on
Linus' releases.

Help with the stable releases is very welcome.

[1] ath9k, ath10k, ath11k etc
