Bug 586

Summary:	Virtio: virtio_dev_rx_queue_done() does not support packed ring

Description Maxime Coquelin 2020-12-03 15:40:35 CET

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.
