I have subsequent patches that add this facility to *fq_codel, pfifo_fast, and elsewhere. It seemed to help somewhat when flooding the box, however I see all sorts of interesting packet fragmentation/defragmentation/splitting stuff happening throughout the 3.6 and 3.7 series of network stack and I have no idea if it's as useful as all that, so I'm willing to drop it and see what happens... What I'd like better though is a multi-exit form of fq_codel that only used one queue allocation for the 4 (or 5 if you count multicast) queues in wifi... but next up is to port forward the prototype to cake... --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
