[dpdk-stable] patch 'cryptodev: fix multi-segment raw vector processing' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/3d67f2c1c3f1ea58d87fcccdb673f045d4f67082

Thanks.

[ upstream commit 8edcb68fd01b6a1e47549be389335cfef042ea05 ]

If no next segment available the “for” loop will fail and it still
returns i+1 i.e. 2, which is wrong as it has filled only 1 buffer.

Fixes: 7adf992fb9bf ("cryptodev: introduce CPU crypto API")
