Description Saravanan KR 2018-03-19 05:19:30 UTC 
Description of problem:
In OSP10, the default mode for vhost-user sockets is "dpdkvhostuser", in which ovs acts as server, which has a drawback of of losing connection when ovs crashes. In OSP11 onwards, the support for "dpdkvhostuserclient" mode has been added which supports ovs in client mode, which can reconnect in case of any failures.
