patch 'telemetry: fix connection parameter parsing' has been queued to stable release 23.11.2

[Xueming Li]

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 08/14/24. 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=f798848548c19b7f7ad896d76c66d7ab678f75b4

Thanks.

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit efdf81829076198189ba6ccbb2e5c50270f56992 ]

For calling memcpy when the source and destination addresses are the same,
there is a small probability that there will be a copy error issue in some
environments, resulting in a failure to connect.

This patch uses memmove instead of memcpy to avoid this issue.

Fixes: b80fe1805eee ("telemetry: introduce backward compatibility")
