Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=108a1722d5781c2c5f7ef0ff42251981d96a9ed8

Thanks.

Subject: [PATCH] app/testpmd: fix outer IP checksum offload
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit b9d859d8a671ec4516face2eba24434b955a9ac1 ]

Resetting the outer IP checksum to 0 is not something mandated by the
mbuf API and is done by rte_eth_tx_prepare(), or per driver if needed.

Fixes: 4fb7e803eb1a ("ethdev: add Tx preparation")
