I'm trying to track down a tricky problem with a Mac book and power save with my ath10k firmware. At least part of the issue is that when the Mac sleeps, it goes into power-save state as far as AP is concerned, and then it simply turns itself off. When it wakes up a short time later, it then tries to scan and re-associate. But, if hostapd hasn't timed out the station (due to longer idle timer), then STA still is treated as being in power-save in the firmware. It appears that this causes mgt-frames (probe responses) not be sent back out of the firmware, so Mac gives up fairly quickly. I fixed at least some of this by forcing a power-save wake on receipt of probe requests and auth requests, but some issues remain for one reason or another. One thing that came to mind: Is it *ever* a good idea to pause a mgt-tid due to power-save? A second non-pausable TID also exists in the firmware...maybe all mgt frames should use that? But if so, then why have a mgt tid at all?
