Hi Holoo,
Can I recommend that you play at bit with VPP's packet tracing facility.
The following wiki page explains setting up the tracer a bit.
https://wiki.fd.io/view/VPP/How_To_Connect_A_PCI_Interface_To_VPP#Show_trace
You will see from tracing a that FD.io VPP exists independently of the
Linux Networking Stack.
With it's own L2 + L3 implementations.

Hi,
According to my researches around VPP and its workflow, I have
prepared a flowchart showing VPP's workflow.
This flowchart says that all ingress packet to interfaces handled by
VPP are sent to VPP without Linux network stack intervention.
afterward based on the packet type/destination one of the flows goes on.
Is this flowchart describing VPP's workflow correctly?? (it might be
helpful if you add more details to it if it's correct OR otherwise
correct it if it's wrong)
thanks in advace
