<p>Hallo,</p>
<p>since this ML has a strong qdisc oriented spin, I'd like to share
what I did end of last year. I was playing a little with BCC/eBPF
and kernel flow interfacing [1] ... excuses for the code quality,
it was prototyping, though ...<br>
</p>
<p>I can imagine reviving efforts as to fleutan, since I perceive
many usefel aspects as to flowing and associations of it are
simply not covered yet, at least no conveniently accessible from
user land end and not on from a per node angle. Especially the
case for backend scenarios with > thousands of flows. Quite
some acre to be plowed if you asked me. Feel free to prove me
wrong. Mostly, I perceive quicker leaps are down to mundane things
like efficient, convenient diggestabilty of low level kernel
interfacing output ... e.g. iproute2. A lot of vibrant dymanics
are perceivable lately in this corner though - I'm applauding.

</p>
<p>Until further progress, might to the merrit of some.<br>
