patch 'app/testpmd: fix GTP L2 length in checksum engine' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/23. 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=9d1fbdb5844757a08a2730c06e5ae88a0885f1ac

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ 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")
