Subject: [dpdk-dev] [PATCH 2/7] net/virtio: add VIRTIO_F_IN_ORDER definition
Date: Fri, 8 Jun 2018 17:07:19 +0800 [thread overview]
Message-ID: <20180608090724.20855-3-yong.liu@intel.com> (raw)
In-Reply-To: <20180608090724.20855-1-yong.liu@intel.com>
If VIRTIO_F_IN_ORDER has been negotiated, driver will use descriptors
in ring order: starting from offset 0 in the table, and wrapping
around at the end of the table.
