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.
