I made an AP where the AP interface acts as a routed interface. I generate traffic through another interface in the router. When sending 300Mbps of 512 byte UDP payloads, in the downstream direction, and with the station being a 1x1 /AC device, then the AP NIC appears to mostly lock up within about 1 minute. I still see beacons, but no data frames. In some cases, I reproduced with very slow speed traffic as well. I tried using a mostly un-modified firmware (ie, similar to upstream QCA), as well as my hacked upon firmware, and all act similarly. I'm using the 4.20 kernel, but at least for now, it does not appear to be a kernel issue. If I use larger MTU sized frames, or have a 2x2 station instead of 1x1 then it is much harder to reproduce (and maybe cannot be reproduced). Also, when generating traffic directly on the AP device instead of using the routed interface as a traffic source, it is harder to reproduce.
