[dpdk-stable] patch 'common/mlx5: fix DevX read output buffer size' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. 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/8d2066d2ec530f74951f54f53b7b48847117681e

Thanks.

Subject: [PATCH] common/mlx5: fix DevX read output buffer size
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit dd9e9d5491858bee49914c4fa574cc8e15640905 ]

Previous patch included a glue function call, with wrong size
calculation for an output buffer.
This patch fixes the issue, using the correct size calculation.

Fixes: bb7ef9a96281 ("common/mlx5: add register access DevX routine")
