[dpdk-dev] [PATCH v2] net/virtio: fix unexpected event after reconnect

[Marvin Liu]

Event notification should be disabled after virtqueue initialization and
enabled by calling rte_eth_dev_rx_intr_enable later. When virtio user
device reconnecting to vhost, virtqueue_disable_intr should be called to
disable event notification.
