Just to follow-up, I ran more experiments since writing the above email and it didn't look like it was doing max() either -- at least on my hardware/firmware combo it had no effect at all that I could tell. I did verify that the wmi update went through to the firmware. I can't remember now, but I may have been testing mesh mode in case that makes a difference. -- Bob Copeland %% https://bobcopeland.com/ _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
