I have put together some of the patches for fq_codel and per-station queuing inside the mac80211 portion of the stack flying around on linux-wireless, to no real visible effect as yet. Mostly testing uploads at the moment, from an x86 based client. It's not clear if I have the code path enabled, either, nor how to check, from userspace. (?) Topology is x86 <-wifi-> wndr3800 <-ethernet-> pi Latency is still poor, throughput is down slightly. I will start printk-ing tomorrow. I do have a few puzzling things A) re the ath9k statistics At the client (ubuntu x86, 4.5-rc7 + patches, Atheros AR5418 Wireless Network Adapter [AR5008E ) I see http://pastebin.com/rvKJnc1y AMPDUs Queued HW: 0 0 0 0 AMPDUs Queued SW: 0 0 0 0 AMPDUs Completed: 1098389 7050 14967 0 At the AP (cerowrt 3.10.50) I see http://pastebin.com/RTt7MNT6 AMPDUs Queued SW: 3009455 364214 557331 0 AMPDUs Completed: 2961055 363353 556982 0 AMPDUs Retried: 115311 7833 21489 0 In both cases the TX-Pkts-all is close to the AMPDUs completed figure. B) In the regular packet captures I see no tcp losses. I can see in an aircap wifi retrying for every lost packet. C) I do not see any ECN marks (presumably would be generated by the codel implementation.) D) I do see things nicely "fq"'d on the captures but that might be by cerowrt rather than the ieee mac E) tc qdisc show dev wlp2s0 shows the tc layer qdisc disabled qdisc noqueue 0: root refcnt 2 which does imply that at least part of the new codepath is working, but there are no stats out of that side yet... Ah, well, at least the patchset compiled and didn't crash the box. -- Dave Täht Let's go make home routers and wifi faster!
