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.


Changes since V1:

- validating all features that depends on ctrl vq
- typo fixes and commit log tweaks
- fix build errors because max_qps is used before it is introduced
