I may have missed other responses, but the single biggest issue with your flow diagram is that there is no Linux network stack interaction unless an agent explicitly configures a logical network interface, or other mechanism, that does.
VPP provides a completely independent packet data-plane which only interacts with Linux as a mechanism to run the code; networking with Linux is completely optional. Chris.

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
