patch 'test/ipsec: fix build with GCC 12' has been queued to stable release 20.11.6

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/22/22. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/df7022dae82dc77ba99c5bb3a3e5d29b219aa51b

Thanks.

[ upstream commit 6e108b6a7c0c0699e6304f7b5706736b34d32607 ]

GCC 12 raises the following warning:

Add a hint so that the compiler understands the copied data is within
the passed string boundaries.
