If no specified, device will not be used as a vDPA device, and it\n+will be driven by virtio pmd.\n+\n+This driver requires the use of VFIO with IOMMU enabled, as a second level\n+of addresses translation is required.\n+\n+Features\n+--------\n+\n+Features of the Virtio vDPA driver are:\n+\n+- Compatibility with virtio 0.95, 1.0 and 1.1.\n+- Multiqueue support.\n+\n+Prerequisites\n+-------------\n+\n+- Platform with IOMMU feature. Virtio device needs address translation\n+ service to Rx/Tx directly with virtio driver in VM or container.\n+\n", "prefixes": [ "15/15" ] }
