Subject: [dpdk-dev] [PATCH] vhost: support Generic Segmentation Offload
Date: Tue, 28 Nov 2017 13:28:33 +0800	[thread overview]
Message-ID: <1511846913-72414-1-git-send-email-jiayu.hu@intel.com> (raw)

In virtio, Generic Segmentation Offload (GSO) is the feature for the
backend, which means the backend can receive packets with any GSO
type.

Virtio-net enables the GSO feature by default, and vhost-net supports it.
To make live migration from vhost-net to vhost-user possible, this patch
enables GSO for vhost-user.
