[PATCH 0/9] virtio_pci: split out legacy device support
virtio 1.0 support for virtio-pci isn't ready yet. Therefore, this patchset doesn't make any functional changes. Instead, this simply refactors virtio-pci, splitting legacy device support code out to a separate file: virtio_pci_legacy.c For virtio 1.0, all that's left is to add virtio_pci_modern.c supporting get_features finalize_features get (config) set (config) get_status
