patch 'test/bbdev: fix crash for non supported HARQ length' has been queued to stable release 21.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/20/23. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/f77e413c9147a5f76f141987ebdb8f316f8afed3

Thanks.

Kevin

Subject: [PATCH] test/bbdev: fix crash for non supported HARQ length

[ upstream commit bee9ac50e5da1f573dfb3c647687da15326d7c3e ]

Fix segmentation fault happening in corner case in test-bbdev.
This fault could happen when running some specific vectors which size
are not supported by the PMD.

Fixes: 335c11fd2763 ("app/bbdev: support HARQ validation")
