Strangely I can't find Timur's version of the patch from patchwork: https://patchwork.kernel.org/project/linux-wireless/list/?state=* Maybe it got dropped due to some UTF-8 problems? patchwork is known to be problematic with UTF-8. Anyway, I'll queue Ryan's v2 to 4.18. It first goes to the pending branch for build testing and from there to ath-current branch. -- Kalle Valo
