(so if you got it, you are inline with our results). I generally switched to using tcp_nup and tcp_ndown (with varying numbers of flows), as well as the various rtt_fair_var tests against multiple stations, to evaluate the wifi changes. It's not clear to me if the quantum and codel targets were restored to their defaults in this release (300->1514, 20ms -> 5ms) > -Aaron > > > > On Mon, Dec 19, 2016 at 2:31 PM, Toke Høiland-Jørgensen <[email protected]> > wrote: >> >> The airtime fairness patch for ath9k has been accepted into the mainline >> Linux kernel, and is queued to be merged for 4.11 (i.e. the next merge >> window after the current 4.10 cycle completes). >> >> The patch has also been accepted into LEDE and is currently in Felix' >> staging tree at >> https://git.lede-project.org/?p=lede/nbd/staging.git;a=summary - so if >> nothing surprising shows up, it should make it into the regular LEDE >> nightlies before too long :) >> >> >> In related news, the Turris Omnia had the WiFi queue restructure patches >> added in the latest update; and the ath10k chip it ships with seems to >> have the required hardware support, so both WiFi devices in the Omnia >> now have nicely debloated queues.
