I think you misunderstand this point. The reason why I avoid it is _not_ anything is missing, quite oppositely, it is because it requires a lot of work to implement a Qdisc with struct_ops approach, literally all those struct Qdisc_ops (not to mention struct Qdisc_class_ops). WIth current approach, programmers only need to implement two eBPF programs (enqueue and dequeue). Thanks.
