patch 'gpudev: export header file for external drivers' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/11/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging/commit/ef700bf7d0b6e90ff72138536ba1703b76905a5e

Thanks.

Subject: [PATCH] gpudev: export header file for external drivers
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 5dd7c0d6956b5c016f48ec62e8c2e81f2a82e10d ]

In DPDK 21.05, the option driver_sdk_headers was introduced
to export required headers to allow building out-of-tree drivers.

In DPDK 21.11, the gpudev driver class was introduced,
without this out-of-tree compatibility.

It is fixed by exporting gpudev_driver.h as part of the driver SDK.

As a consequence of exporting this header file,
C++ "extern C" guard must be added.

Fixes: 8b8036a66e3d ("gpudev: introduce GPU device class library")
