vhost-vDPA is a new virtio backend type introduced by vDPA kernel framework, which provides abstraction to the vDPA devices and exposes an unified control interface through a char dev. This patch adds support to the vhost-vDPA backend. As similar to the existing vhost kernel backend, a set of virtio_user ops were introduced for vhost-vDPA backend to handle device specific operations such as: - device setup - ioctl message handling - queue pair enabling - dma map/unmap vDPA relevant ioctl codes and data structures are also defined in this patch.
