In case of issue in VPP it is possible that no reply is returned, and Honeycomb waits for reply indefinitely.

Currently can be reproduced by adding the local0 interface to a bridge domain with bridged-virtual-interface set to True. (https://jira.fd.io/browse/VPP-159):

1. create bridge domain:
"bridge-domain": [

{ "name": "bd-01", "flood": true, "arp-termination": true, "forward": true, "unknown-unicast-flood": true, "learn": true }

,
2. add local0 to bridge domain with bvi=True:
{
"name": "local0",
"type": "iana-if-type:ethernetCsmacd",
"enabled": "false",
"v3po:l2":

{ "bridge-domain": "bd-01", "split-horizon-group": "1", "bridged-virtual-interface": "true" }

},
