You can reference reassembly code, which does something similar.

Hi ,
We are having a scenario to support as below and we would like to know what we
are doing here is correct or not.
1. Our graph node receives a frame with TWO buffers
2. Graph node decides to process FIRST buffer and enqueues the packet to a
next-node.

Hello all,
It's time to begin the preparations for the 20.05 VPP release.
According to the agreed release plan [1], the API freeze will happen
on the May 6, 2020, at 18:00 UTC,
so this is a first gentle reminder.
We are now just slightly more than three weeks before that milestone.

Running on 2 sibling threads on haswell/bradwell usually gives around 10% more
performance, and on skylake/cascadelake number is 20% or more.
Caveat is that you need to rely on RSS or some other mechanism do equally

We usually only run worker threads on sibling cores - workers should be
Hi Prashanth,
It depends of your CPU. We usually recommend to disable hyperthreading for

should run 2 workers per physical core, 1 per hyper-thread. You can find more
