This patch updates qos-scripts to support fair traffic sharing using the SFQ with external classifiers method. It also corrects a bug in the unsupported ESFQ method already used by qos-scripts. (ESFQ: http://fatooh.org/esfq-2.6/ only updated to 2.6.24, it was switched to an SFQ patch after that and not updated since 2008)
A class can be forced to use SFQ, and an external classifier added like this: config class "Normal" option avgrate 10 option priority 30 option packetdelay 100 option limitrate 94 # option qdisc "sfq perturb 2" config class "Normal_up" # option filter "protocol all flow hash keys src divisor 1024" config class "Normal_down" # option filter "protocol all flow hash keys dst divisor 1024" Using these options, the user needs to load cls_flow before qos-scripts starts. I've got more information here: http://oneitguy.com/blogs/netprince/fair-traffic-sharing-esfq-broken-switching-sfqexternal-classifiers This has been tested on r23914.
