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@dpdk.org
Reporter: maxime.coquelin@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.
