[dpdk-stable] patch 'vhost: fix vector filling for packed ring' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/28/18. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Kevin Traynor

Subject: [PATCH] vhost: fix vector filling for packed ring

[ upstream commit 16b9e38e74147fb004fa112c055b2fd500403b36 ]

We should return the length of the buffers described by
the current descriptor chain after filling the buffer
vector. So we need to zero the *len first.
