Hi,
FYI, your patch has been queued to stable release 21.11.6
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/21/23. 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/ac5c77407216ea99446ea7b776d665f8605921e7
Thanks.
Kevin

Subject: [PATCH] app/testpmd: add explicit check for tunnel TSO
[ upstream commit 33156a6bc61560e74a126ade38a7af9c1fa02671 ]
If port don't support TSO of tunnel packets, tell user in advance and no
need to change other configuration of this port in case of fault spread.
In addition, if some tunnel offloads don't support, which is not an
error case, the log about this shouldn't be to stderr.
Fixes: 3926dd2b6668 ("app/testpmd: enforce offload capabilities check")
