Subject: [dpdk-dev] [PATCH v4 18/26] virtio: Fix descriptor index issue
Date: Mon,  9 Feb 2015 09:14:07 +0800	[thread overview]
Message-ID: <1423444455-11330-19-git-send-email-changchun.ouyang@intel.com> (raw)
In-Reply-To: <1423444455-11330-1-git-send-email-changchun.ouyang@intel.com>

It should use vring descriptor index instead of used_ring index to index vq_descx.
