I really don't remember - forgive me if I've forgotten who actually leaned in on it) written a basic ack-filter in ebpf. this was before cake gained tc actions and my primary use for the tech was for asymmetric connections, and before the good ack-filter arrived, and I was (and remain) unfriendly to this level of dpi. That said, on a symmetric connection, deprioritizing pure acks to the 5% background queue nd then turning the cake ack-filter loose on it might actually work. Am I on drugs/is there any point? --=20 I tried to build a better future, a few times: https://wayforward.archive.org/?site=3Dhttps%3A%2F%2Fwww.icei.org Dave T=C3=A4ht CEO, TekLibre, LLC
