It's essentially above. I think you can actually do it in pure bpf without skbedit, I'd written a tc bpf flow classifier for acks quite some time ago. The not current version is attached. I really need to finish up some ack related stuff. Using a bpf map to this then setting the flowid directly? > This wouldn’t give both per-member and per-flow fairness, but at least > per-member fairness might be possible.
