But it is not easy, because I need to use a cross-compiler. From openwrt website I can download a backport 2015-05-08. I will try to integrate it. > > Do you know how I can generate a tar file for openwrt from kale git hub? That's non-trivial as far as I understand. You could try generating a quilt patch in openwrt to update ath10k. Either some sort of manual cherry-picking of the txmode patch for ath10k or create a partial diff (e.g. only drivers/net/wireless/ath/ath10k) between openwrt backports and kvalo/ath generated backports.
