I am under the impression that the ag71xx does not support jumbo frames. Slightly larger than usual frames? dunno. the ath9k supports frames up to the size of the wireless standards (23xx bytes or so) 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. > > Thanks > > -- > Alessandro Bolletta > Mediaspot S.r.l. > > > _______________________________________________ > Codel mailing list > Codel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/codel --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
