Hi,

FYI, your patch has been queued to stable release 22.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/16/24. 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/0c972805e14e02a6774bac91be5cd977058f8ee5

Thanks.

Luca Boccassi

Subject: [PATCH] app/testpmd: return if no packets in GRO heavy weight mode

[ upstream commit 0007e4045c9efe6a20ad2590dfa68a86cc778b48 ]

If there are no packets flushed in GRO heavy weight mode,
return false as this fall through code would return true
indicating that packets are available

Fixes: 461c287ab553 ("app/testpmd: fix GRO packets flush on timeout")
