[PATCH] net/vhost-user: Save ack_features to net_clients during vhost_user_start

Posted by Yi Wang 2 years ago

From: Liu Xiangyu <liu.xiangyu2@zte.com.cn>

During vhost_user_start, if openvswitch.service restart, cause the final features
not expected. Because qemu not save the ack_features promptly.
