	  This provides migration support for VIRTIO NET PCI VF devices
	  using the VFIO framework. Migration support requires the
	  SR-IOV PF device to support specific VIRTIO extensions,
	  otherwise this driver provides no additional functionality
	  beyond vfio-pci.

	  Migration support in this driver relies on dirty page tracking
	  provided by the IOMMU hardware and exposed through IOMMUFD, any
	  other use cases are dis-recommended.

	  If you don't know what to do here, say N.

	  This extends the virtio-vfio-pci driver to support legacy I/O
	  access, allowing use of legacy virtio drivers with VIRTIO NET
	  PCI VF devices. Legacy I/O support requires the SR-IOV PF
	  device to support and enable specific VIRTIO extensions,
	  otherwise this driver provides no additional functionality
	  beyond vfio-pci.
