As stated I am not sure whether that is a relevant layering violation to begin with… I believe that Jonathan found a way to have a dscp qdisc stacked on top of cake that does the squashing afterwards. I am uncertain whether that only worked in theory (so whether research stopped after finding the dscp qdisc) or whether that was actually tested to DTRT in allowing cake to use the internally set DSC values but re-map them to 0 before putting them on the wire?
