Hi,
FYI, your patch has been queued to stable release 21.11.6
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/12/23. 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://github.com/kevintraynor/dpdk-stable
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/fab24e72ab032170f162e7755efe7c00b8dea989
Thanks.
Kevin

Subject: [PATCH] app/pipeline: add sigint handler
[ upstream commit f6897b23f70b84742129a215ea2be17c8843adb8 ]
For test-pipeline, if the main core receive SIGINT signal, it will kill
all the threads immediately and not wait other threads to finish their
jobs.
To fix this, add 'signal_handler' function.
Fixes: 48f31ca50cc4 ("app/pipeline: packet framework benchmark")
