Qemu get virtio_net_config from the vdpa driver. So The vdpa driver
should set the VIRTIO_NET_S_LINK_UP flag to virtio_net_config like
vdpa_sim. Or the link of virtio net NIC in the virtual machine will
never up.

Please keep CCing netdev on future submissions, but the vdpa patches
actually go through Michael's tree, so make sure to CC
