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. Signed-off-by: Xiaolong Ye <xiaolong.ye@intel.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com>
