Hi,

FYI, your patch has been queued to stable release 19.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before December 10th 2021. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/c98edab429c991ee3b2e22fff3c3a688e224d00d

Thanks.

Subject: [PATCH] examples/l3fwd-power: fix early shutdown

[ upstream commit 19781e7a038ac3fdae4d71904268daa6ee399001 ]

Currently, EAL init cannot be interrupted with SIGINT because the
signal handler is already overridden by the time EAL init happens.

Fix it by moving signal handler installation to after EAL
initialization, to allow SIGNIT to interrupt EAL initialization.

Fixes: d7937e2e3d12 ("power: initial import")
Fixes: 613ce6691c0d ("examples/l3fwd-power: implement proper shutdown")
