	With a functional and tested backend for virtio-block live migration, add the virtio-block device ID to the pci_device_id table. Currently, the driver supports legacy IO functionality only for virtio-net, and it is accounted for in specific parts of the code. To enforce this limitation, an explicit check for virtio-net, has been added in virtiovf_support_legacy_io(). Once a backend implements legacy IO functionality for virtio-block, the necessary support will be added to the driver, and this additional check should be removed. The module description was updated accordingly.

2024-11-13	vfio/virtio: Enable live migration once VIRTIO_PCI was configured	Yishai Hadas
	Now that the driver supports live migration, only the legacy IO functionality depends on config VIRTIO_PCI_ADMIN_LEGACY. As part of that we introduce a bool configuration option as a sub menu under the driver's main live migration feature named VIRTIO_VFIO_PCI_ADMIN_LEGACY, to control the legacy IO functionality. This will let users configuring the kernel, know which features from the description might be available in the resulting driver. As of that, move the legacy IO into a separate file to be compiled only once CONFIG_VIRTIO_VFIO_PCI_ADMIN_LEGACY was configured and let the live migration depends only on VIRTIO_PCI.
