I'm doing a test with 200 virtual stations on each of 6 ath9k radios. When I configure stations for DHCP, I see cases where stations on a particular radio will not transmit anything sometimes. I see no 'XMIT' logs that show indication of frames being received in the driver from the upper stack, but if I use 'tshark' on a station interface, it shows frames being 'transmitted'. I do, however, see this, which looks like it might show an issue. It looks like whatever 'aqm' is, it has an ever expanding number of backlog packets: [root@2u-6n lanforge]# cat /debug/ieee80211/wiphy2/netdev\:sta30194/stations/00\:0e\:8e\:69\:b8\:f7/aqm target 49999us interval 299999us ecn no tid ac backlog-bytes backlog-packets new-flows drops marks overlimit collisions tx-bytes tx-packets 0 2 27616 440 9 0 0 0 428 998 7 1 3 0 0 0 0 0 0 0 0 0 2 3 0 0 0 0 0 0 0 0 0 3 2 0 0 0 0 0 0 0 0 0 4 1 0 0 0 0 0 0 0 0 0 5 1 0 0 0 0 0 0 0 0 0 6 0 0 0 1 0 0 0 0 390 1 7 0 0 0 637 0 0 0 792 22072 903 8 2 0 0 0 0 0 0 0 0 0 9 3 0 0 0 0 0 0 0 0 0 10 3 0 0 0 0 0 0 0 0 0 11 2 0 0 0 0 0 0 0 0 0 12 1 0 0 0 0 0 0 0 0 0 13 1 0 0 0 0 0 0 0 0 0 14 0 0 0 0 0 0 0 0 0 0 15 0 0 0 0 0 0 0 0 0 0 Anyone have any pointers as to whether this might be a real issue or not? I'll go digging in the meantime.... Thanks, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com
