[dpdk-stable] patch 'net/mlx5: reject inner ethernet matching in GTP' has been queued to stable release 20.11.3

Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/28/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/d0213e26bbb0d02d4c811527e8c3a7b014aca3c4

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: reject inner ethernet matching in GTP

[ upstream commit 4e5ba38d56e3a037271547c90fbfc25c81938a4f ]

The user is able to create a flow rule pattern with ETH after GTP
although it is not supported by the flex-parser configuration.

Failed the rule validation in such case with proper error message.

Fixes: 23c1d42c7138 ("net/mlx5: split flow validation to dedicated function")
