            Bug ID: 586
           Summary: Virtio: virtio_dev_rx_queue_done() does not support
                    packed ring
           Product: DPDK
           Version: 19.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: vhost/virtio
          Assignee: dev at dpdk.org
          Reporter: maxime.coquelin at redhat.com
  Target Milestone: ---

virtio_dev_rx_queue_done() is the Virtio callback for
rte_eth_dev->rx_descriptor_done.

The issue is that it assumes Split ring is used, which would cause undefined
behaviour when packed ring has been negotiated.
