[dpdk-stable] patch 'app/testpmd: fix tunnel offload flows cleanup' 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 06/14/21. 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/18151dfdcb4ed88b44d7c21244442dad671b8d36

Thanks.

Subject: [PATCH] app/testpmd: fix tunnel offload flows cleanup
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 99fc79b37af5652f30ab3c9725fd6a98494d14dc ]

Tunnel offload model requires application to obtain PMD related flow
items or actions to construct a flow rule. These elements acquire
internal PMD flow resources that must be explicitly released.

The patch destroys tunnel offload PMD resources after flow creation
failure.

Fixes: 1b9f274623b8 ("app/testpmd: add commands for tunnel offload")
