Not clear if either of these devices write the device itself directly (where's the ring buffer?) or use an overlying qdisc (seems unlikely). At least a few other devices are using vpp that I know of. vpp ripped out support for even RED a few years back. hqos is deprecated. What if anything replaced it? --=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
