We are thinking to implement jumbo frames support on some devices based on ag71xx :) Many SoCs support up to 2028 bytes or 4076 bytes of MTU but the driver still can't manage MTUs higher than 1518bytes. >the ath9k supports frames up to the size of the wireless standards (23xx bytes >or so) Yes. >fq_codel's internal quantum is the actual ip packet size, not the wire size. >at lower bandwidths it pays to have a lower quantum (like 300) on outgoing >interfaces. >In openwrt the default on all interfaces is 300, which I dont necessarily >agree with. Ok. I thought that codel would leverage on layer-2 parameters, as the size of the ethernet frame. > > Thanks > > -- > Alessandro Bolletta > Mediaspot S.r.l. > > > _______________________________________________ > Codel mailing list > [email protected] > https://lists.bufferbloat.net/listinfo/codel -- Dave Täht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.html _______________________________________________ Codel mailing list [email protected] https://lists.bufferbloat.net/listinfo/codel
