Sorry for the delay, my plan was to first write some documentation about different hardware families but haven't managed to do that yet. My problem with this patch is that I don't know what hardware and firmware versions were tested, so it needs analysis before I feel safe to apply it. The ath10k hardware families are very different that even if a patch works perfectly on one ath10k hardware it could still break badly on another one. What makes me faster to apply ath10k patches is to have comprehensive analysis in the commit log. This shows me the patch author has considered about all hardware families, not just the one he is testing on, and that I don't need to do the analysis myself. -- https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
