Hi,
FYI, your patch has been queued to stable release 22.11.2
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging
This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=ad62d3f41062dd1cd4354c75ad89fae6fc289b12
Thanks.

Subject: [PATCH] app/compress-perf: fix testing single operation
Cc: Xueming Li <xuemingl at nvidia.com>
[ upstream commit 83cc3b90ad7a63868a43a67d6aa13b55068fbe0c ]
Part of the application options is to test only compress and only
decompress but actually the application ignores this user option and
tries to test always both compress and decompress.
Allow testing only compress and only decompress.
Fixes: e0b6287c035d ("app/compress-perf: add parser")
