patch 'eventdev: add missing C++ guards' has been queued to stable release 19.11.12

[christian.ehrhardt@canonical.com]

Hi,

FYI, your patch has been queued to stable release 19.11.12

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/11/22. 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/5d5711a19a1a975ec86948db1aa8896ea2f27bc8

Thanks.

Subject: [PATCH] eventdev: add missing C++ guards

[ upstream commit 2c552933ba453984c26262136150d75235f6aabe ]

Some public header files were missing 'extern "C"' C++ guards,
and couldn't be used by C++ applications. Add the missing guards.

Fixes: dc39e2f359b5 ("eventdev: add ring structure for events")
Fixes: 7a3357205755 ("lib: remove C++ include guard from private headers")
