patch 'examples/ipsec-secgw: fix NAT-T header fields' has been queued to stable release 21.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/22. 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/be3beb946efd3a028b5a901bcd2494b30d7f32ac

Thanks.

Kevin

Subject: [PATCH] examples/ipsec-secgw: fix NAT-T header fields

[ upstream commit 5051dc42a193551a837f7a4c0a1726babde46ae6 ]

Use the proper IP protocol (UDP instead of ESP) and set the ports when
UDP encapsulation is enabled.

Fixes: 9ae86b4cfc77 ("examples/ipsec-secgw: support UDP encap for inline crypto")
