Those cover most of the identified issues for drivers using mac80211
(e.g., ath9k and ath10k; though, I don't remember whether I actually
ever managed to reproduce this with ath10k in practice). I have couple
of additional ath9k-specific patches that cover additional lower layer
paths for this. I hope to get those out after confirming they work with
the current kernel tree snapshot.
