patch 'app/testpmd: fix tunnel TSO capability check' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/13/23. 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=6f1c35e7a802084271fedcfcf9590785d8c30723

Thanks.

Subject: [PATCH] app/testpmd: fix tunnel TSO capability check
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 6d4def820aa7d118f1ebdebf7af8ba6299ac20ee ]

Currently, testpmd set tunnel TSO offload even if fail to get dev_info.
In this case, the 'tx_offload_capa' in dev_info is a random value,

Fixes: 6f51deb903b2 ("app/testpmd: check status of getting ethdev info")
