I do not understand why there is a "fast path" at all in this driver, should we always wait a little bit to see if we can form an aggregate? It would be awesome to be able to adapt michal's work on fq_codeling things as he did here (leveraging rate control information) http://blog.cerowrt.org/post/fq_codel_on_ath10k/ rather than dql as he did here: http://blog.cerowrt.org/post/dql_on_wifi_2/ to the ath9k. > -Toke > _______________________________________________ > Make-wifi-fast mailing list > Make-wifi-fast@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/make-wifi-fast --=20 Dave T=C3=A4ht Let's go make home routers and wifi faster!
