As qemu will only send VHOST_USER_SET_VRING_ENABLE message for guest enabled vrings (only first queue pair will be enabled at initialized stage), this will cause trouble for multiqueue case, vDPA's dev_conf callback will get no chance be invoked. Decouple the dev_conf callback from VHOST_USER_SET_VRING_ENABLE solves this issue.
