+Virtio vDPA driver
+==================
+
+The Virtio vDPA driver provides support to either para-virtualized
+or fully HW offloaded Virtio-net devices.
+
+Pre-Installation Configuration
+------------------------------
+
+Config File Options
+~~~~~~~~~~~~~~~~~~~
+
+The following option can be modified in the ``config`` file.
+
+- ``CONFIG_RTE_VIRTIO_VDPA`` (default ``y`` for linux)
+
+Virtio vDPA Implementation
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To let the Virtio-net device being probed by the Virtio vDPA driver, adding
+"vdpa=1" parameter helps to specify that this device is to be used in vDPA
+mode, rather than polling mode, virtio pmd will skip when it detects this
+message. If no specified, device will not be used as a vDPA device, and it
+will be driven by virtio pmd.
+
+This driver requires the use of VFIO with IOMMU enabled, as a second level
+of addresses translation is required.
+
+Features
+--------
+
+Features of the Virtio vDPA driver are:
+
+- Compatibility with virtio 0.95, 1.0 and 1.1.
+- Multiqueue support.
+
+Prerequisites
+-------------
+
+- Platform with IOMMU feature. Virtio device needs address translation
+ service to Rx/Tx directly with virtio driver in VM or container.
