patch 'ethdev: add missing C++ guards' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/06/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/b99a45df054af0cb5b847e7d9b87bf95c2e345d4

Thanks.

Kevin

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

[ upstream commit dbf9fc1dac70b64dd1ed9a3ffd6997838fbf170e ]

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

Fixes: 7a3f27cbf59b ("ethdev: add access to specific device info")
Fixes: dcd5c8112bc3 ("ethdev: add PCI driver helpers")
Fixes: 7f0a669e7b04 ("ethdev: add allocation helper for virtual drivers")
Fixes: 7a3357205755 ("lib: remove C++ include guard from private headers")
