that didn't work either :(
we cannot replace skb via skb_share_check() inside cls/act. We cannot do
it inside ingress_enqueue() either. It can only be done at handle_ing()
level. And it's quite ugly to change the signatures of the whole
qdisc->enqueue() call chain just for cls_bpf. May be introducing
bpf-only ingress qdisc to decouple the logic is not such a bad idea?
Then ing_filter() can special case it just like != noop_qdisc.
Or a flag for existing ingress qdisc? Will see how it looks.
