H A Dvhost-vdpa.c8801ccd0 Sat Oct 08 02:58:58 CDT 2022 Si-Wei Liu <si-wei.liu@oracle.com> vhost-vdpa: allow passing opened vhostfd to vhost-vdpa

Similar to other vhost backends, vhostfd can be passed to vhost-vdpa
backend as another parameter to instantiate vhost-vdpa net client.
This would benefit the use case where only open file descriptors, as
opposed to raw vhost-vdpa device paths, are accessible from the QEMU
process.
