This patch adds new schema and adds support for parsing and formatting domain configurations that include vdpa devices.
vDPA network devices allow high-performance networking in a virtual machine by providing a wire-speed data path. These devices require a vendor-specific host driver but the data path follows the virtio specification.
When a device on the host is bound to an appropriate vendor-specific driver, it will create a chardev on the host at e.g. /dev/vhost-vdpa-0. That chardev path can then be used to define a new interface with type='vdpa'.
