Description
===========
-Vhost event idx interrupt need test with l3fwd-power sample, send small packets from virtio-net to vhost side，check vhost-user cores can be wakeup status，and vhost-user cores should be sleep status after stop sending packets from virtio side.

+from virtio-net to vhost side，check vhost-user cores can be wakeup status，and
