[dpdk-stable] patch 'net/mlx5: fix hashed list size for tunnel flow groups' 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/1cac75b516d87568beb9d946a6f8700f422b9d86

Thanks.

Subject: [PATCH] net/mlx5: fix hashed list size for tunnel flow groups
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit c86e5b90125890f950892e890e8859d87d63140b ]

The hashed list size must be the power of 2, otherwise the
adjustment is applied and the warning message is emitted.
This patch provides the correct list size to eliminate the
warning.

Fixes: 4ec6360de37d ("net/mlx5: implement tunnel offload")
