patch 'app/testpmd: handle IEEE1588 init failure' has been queued to stable release 21.11.8

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/af2127b83fe7a4f1b77ec920889f6ce86a2894ed

Thanks.

Kevin

Subject: [PATCH] app/testpmd: handle IEEE1588 init failure

[ upstream commit 80071a1c8ed669298434c56efe4ca0839f2a970e ]

When the port's timestamping function failed to initialize
(for example, the device does not support PTP), the packets
received by the hardware do not contain the timestamp.
In this case, IEEE1588 packet forwarding should not start.
This patch fix it.

Plus, adding a failure message when failed to disable PTP.

Fixes: a78040c990cb ("app/testpmd: update forward engine beginning")
