Besides, please cc corresponding maintainers while sending patches, say cc me for virtio/vhost changes. From MAINTAINERS you could find the names. So, please make a v2, with above 2 minor fixed. And also, please follow the guide on http://dpdk.org/dev to send v2: If a previous version of the patch has already been sent, a version number and changelog annotations are helpful: git send-email -1 -v2 --annotate --in-reply-to <Message-ID of the previous patch> --to dev at dpdk.org --cc <everybody discussing the patch> --yliu
