I'm not sure if vhost-user is designed to support live migration in the first place. It's only worth adding ARP packet injection support if live migration is supported with vhost-user. You don't need to define a queue, instead implement the .receive() function for vhost-user and invoke a new virtio-net-specific vhost-user request type that injects a packet (independent of the tx virtqueue).
