Do we need patch qemu for the reconnect case?  

Thanks

Subject: [dpdk-dev] [PATCH 0/6] vhost: add vhost-user client mode and reconnect ability

Both the vhost-user backend (DPDK here) and frontend (QEMU) could be server, as well as client. DPDK just acts as server so far. This patch set would make it possible to act as both.

A new arg (flags) is introduced for API rte_vhost_driver_register(). And the client mode is enabled when RTE_VHOST_USER_CLIENT is given. Note that this implies an API breakage. However, since this release deals with ABI/API refactoring, it should not be an issue.

With the DPDK as client, it's easier to implement the "reconnect" ability, which means we could still make vhost-user work after DPDK restarts.
