  Vhost-vDPA support in Virtio-user PMD was lacking
backend features negotiation and IOTLB batching
support, causing intialization issues with Mellanox
vDPA device managed by Kernel vDPA framework.

Changes in v3:
=============
- Fix protocol features negotiation condition (Chenbo)
- Fixup comment in struct declaration (Chenbo)

Changes in v2:
=============
- Add backend features negotiation (David, Jason)
- Ensure Kernel supports IOTLB MSG v2

Maxime Coquelin (2):
  net/virtio: fix missing backend features negotiation
  net/virtio: fix memory init with vDPA backend
