Hi All: This patch implements the multiqueue support for vhost-vDPA. The most important requirement the control virtqueue support. The virtio-net and vhost-net core are tweak to support control virtqueue as if what data queue pairs are done: a dedicated vhost_net device which is coupled with the NetClientState is intrdouced so most of the existing vhost codes could be reused with minor changes. With the control virtqueue, vhost-vDPA are extend to support creating and destroying multiqueue queue pairs plus the control virtqueue. Tests are done via the vp_vdpa driver in L1 guest plus vdpa simulator on L0. Please reivew.
If no objection, I will queue this for 6.1. Thanks
