In a router-gateway-attached network, tap interfaces of vms get deleted immediately

[Vedamurthy Joshi]

R2.0 Build 16 Multi-node Ubuntu 14.04 setup

Was trying the below script :
scripts.neutron.test_routers.TestRouters.test_basic_snat_behavior

It was seen that when router-gateway was enabled, when a VM is launched in a network attached to the router, the tap interface gets created, but gets deleted immediately in about a min

Praveen, Hari know the issue. This looks related to recent agent audit-related changes.

In ContrailVRouterApi, do a connect to the Agent only when the add port / delete port request comes from nova_contrail_vif.
For other requests, do not invoke connect. In case we do a connect and do not send complete vif list, Agent removes them
upon audit. Also, set port_type to NameSpacePort, if it isnt specified.
