[dpdk-stable] patch 'vfio: fix FreeBSD clear group stub' 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 11/12/21. 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/bef6f8c951463c9c99449553b2ab95c812643309

Thanks.

Subject: [PATCH] vfio: fix FreeBSD clear group stub
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit bf8b792f3b8519fecf3585ffac15da6f7bca2de9 ]

On FreeBSD, `rte_vfio_clear_group()` was returning 0 even though this
function is not valid for FreeBSD, and is called out to return error in
doxygen comments.
Fix the return value to match documentation.

Fixes: c564a2a20093 ("vfio: expose clear group function for internal usages")
