Occurs in csit func test since:

https://gerrit.fd.io/r/#/c/9568/

or

https://gerrit.fd.io/r/#/c/9569/

Failed test:

https://jenkins.fd.io/view/hc2vpp/job/hc2vpp-csit-integration-master-ubuntu1604/1237/

Issue is reproducible locally. Looks like vpp bug or non documented behaviour change that HC needs to adapt to.
