We've discussed this internally and we can add/(replace OVSDPDK+ODL job) with a 'tempest-dsvm-full-nfv' one (currently running on Nova changes) that does devstack + runs full tempest test suite (1100+ tests) on NFV enabled flavors. It should test properly proposed devstack changes with NFV features (as per wiki [4]) we have enabled in Openstack.
