patch 'test/bbdev: extend HARQ tolerance' has been queued to stable release 20.11.8

Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/17/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/83969dbe773464e827abf2816346532b372486dd

Thanks.

Luca Boccassi

Subject: [PATCH] test/bbdev: extend HARQ tolerance

[ upstream commit 39b601c462b8192b8f1c98fe26b604430ebcc8e4 ]

HARQ memory implementation could have different size assumptions.
Extending HARQ tolerance to cover different implementations.

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