[Qemu-devel] [PATCH RFCv2 5/9] virtio-pci: Allow to specify additional interfaces for the base type

[David Hildenbrand <david@redhat.com>]

Let's allow to specify additional interfaces for the base type (e.g.
later TYPE_MEMORY_DEVICE), something that was possible before the
rework of virtio PCI device instantiation.
