patch 'examples/l3fwd-power: fix early shutdown' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/21. 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/e4f79de95a24b9d6030957cef4826623abd664f3

Thanks.

Subject: [PATCH] examples/l3fwd-power: fix early shutdown
Cc: Xueming Li <xuemingl at nvidia.com>

[ 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")
