First of all, I can't reproduce these problems reliably. One evening I got WARNINGs one by one and I could work on my debugging patch easily. Yesterday when I got my patch complete, it took me 10+ hours to get a single WARNING.
I think I found a way to reproduce this more reliably! It seems doing a static transfer from few devices (I use iperf) doesn't matter much. So this is what I do to get WARNINGs on my DIR-885L: 1) Notebook sending data with iperf to DIR-885L 2) iPad playing YouTube using SR400ac on the same channel 3) I take my 2 smartphones to the next room and keep switching between 2 out of 3 SSIDs of DIR-885L. Once connected I run iperf for a bit randomly. It seems I can get a WARNINGs every few minutes this way.
Enough talking, please take a look at my debugging log. Does it give you enough hint? Could you review/debug firmware's code responsible for AMPDU? FWIW Merlin users (so no brcmfmac invovled) also saw this [1].
I grabbed more logs I can share now. I believe they show the same: stall and warning soon after ampdu_dbg/wlc_ampdu_watchdog. I'm attaching them anyway. Please note that calls to __send_key_to_dongle happen all the time, I'm including them in logs for a context. You can treat them as an indicator that things are going well. It's ampdu_dbg + wlc_ampdu_watchdog that lead up to the WARNINGs.
