  This patch series makes Virtio-user works in IOVA as PA mode
for vDPA backend.

First patch fixes the issue when having buffer IOVA address in
control queue descriptors.
Second and third patches helps to share descriptor IOVA address,
to the vhost backend. And also disables the use_va flag for VDPA
backend type.

v1->v2:
- Split single patch into three patches.

Srujana Challa (3):
  net/virtio_user: avoid cq descriptor buffer address accessing
  net/virtio: store desc IOVA address in vring data structure
  net/virtio_user: support sharing vq descriptor IOVA to the backend
