+* **Added vhost-user client mode.**
+
+ DPDK vhost-user could be the server as well as the client. It supports
+ server mode only before, now it also supports client mode. Client mode
+ is enabled when ``RTE_VHOST_USER_CLIENT`` flag is set while calling
+ ``rte_vhost_driver_register``.
+
+ When DPDK vhost-user restarts from normal or abnormal quit (say crash),
+ the client mode would allow DPDK to establish the connect again. Note
+ that a brand new QEMU version (v2.7 or above) is needed, otherwise, the
+ reconnect won't work.
