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.
