Please could you describe what is a modern virtio-net?
> #define VIRTIO_PCI_DEVICEID_MIN 0x1000
> #define VIRTIO_PCI_DEVICEID_MAX 0x103F
> +#define VIRTIO_PCI_MODERN_DEVICEID_NET 0x1041
It doesn't match the sentence above: 1000 + 1040 = 2040
By the way, VIRTIO_PCI_DEVICEID_MAX is not used in the code.
