Hi,

FYI, your patch has been queued to stable release 20.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/17/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/75a452410f544c5fd459c5d0f68023ae108cdc34

Thanks.

Luca Boccassi

Subject: [PATCH] app/testpmd: fix GTP L2 length in checksum engine

[ upstream commit dd827fa42a30a9b0aa87a1d5614af83ea32b19e0 ]

GTP header can be followed by an optional 32 bits extension.

But, l2_len value statically set to RTE_ETHER_GTP_HLEN
which is defined to be
        (sizeof(struct rte_udp_hdr) + sizeof(struct rte_gtp_hdr))

This fixes the l2_len to take into consideration the extension size.

Fixes: d8e5e69f3a9b ("app/testpmd: add GTP parsing and Tx checksum offload")
