Well, the core portion of the patch's intent was to reduce bufferbloat-related latency at low rates, without costing throughput. I am curious (if artificially limited somehow), if any results even vaguely similar to to the initial effort and final paper - are coming out of this version against this chipset. initial POC: http://blog.cerowrt.org/post/fq_codel_on_ath10k/ final paper: https://www.usenix.org/system/files/conference/atc17/atc17-hoiland-jorgensen.pdf > _______________________________________________ > Lede-dev mailing list > Lede-dev@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/lede-dev _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
