DSL - Jeesper's overhead as noted in the comments is not 5 and anyway I= =20 think his good work has now been superseded by stab as it allows for=20 negative overheads, which his did not. man tc-stab has clear and good explanations and examples. SFQ - well it's literally been years since I knew it in detail, but=20 limit was (back then at least) for all flows combined. I tested (maybe not hard enough) quantum < mtu and never managed to=20 prevent dequeues - I know it's not efficient and "forbiden" but back=20 then at least it didn't break. Anyway it seems that early this year SFQ got some love and now has=20 several more options (red, headdrop, limit >127, depth as param) - so a= s=20 long as your iproute/kernel is current have a look at man tc-sfq for=20 details.
