Help text

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.

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