patch 'vhost: fix C++ include' 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 02/26/22. 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/c59904ed037588d2b513b37675a322120b82e273

Thanks.

Kevin

Subject: [PATCH] vhost: fix C++ include

[ upstream commit 1d1126ad436e8c7c015fb3f67ad3af05c3b397d5 ]

The virtio kernel header includes are already noted as being
incompatible with C++. We can ensure that the header is safe for
inclusion in C++ code by not including those headers during C++ builds.
While not ideal, this does ensure that all DPDK headers can be included
in C++ code without errors.

Fixes: f8904d563691 ("vhost: fix header for strict compilation flags")
