Followup from the netdev1.1 conference in Seville: looks like we kicked some people into finally getting some of their low-latency patches going.  Dave Taht analyzes Michal Kazior's work getting fq_codel working with per-station queues on ath10k, and the results are pretty great: http://blog.cerowrt.org/post/fq_codel_on_ath10k/

Still some latency trouble though, particularly when mixing low- and high-signal strength stations.
