Folks,
I have configuring my system to get something comparable to CSIT
performance and I am a few mpps off at the moment, using FD.io VPP 18.07.
I duplicated the IPv4 Base and Scale Test Cases (and environment)
locally and I end up with extra graph node 'ip4-load-balance' in my
pipeline?
CSIT records the following pipeline in Test Operation Data.

I get the following pipeline, with the additional graph node -
ip4-load-balance.

Any idea where ip4-load-balance is coming from?
