My principal objective for the past week was to "make it crash", and this is the longest the archer has ever survived intensive testing. wmm on and off, multiple stations, 3 different distances, two to six different clients, multicast rates set higher, ath9k and ath10k, routed vs bridged (haven't returned to bridged), through the device, to the device, channel scans, no channel scans, single queue vs multi-queue, through sqm (with cake or fq_codel) and over the local lan, ecn vs noecn, and I haven't got to blowing up multicast with uftpd yet nor thc-ipv6. Figuring out *why* things behaved badly was secondary, and kind of hard, when they did. But no cases of RUD since jan 30. thank ghu (and toke) for flent! And things are looking the most solid they've ever been. As for whether this patch actually accomplished anything or not... tell you in 24 hours.
