Hi,

FYI, your patch has been queued to stable release 20.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/19/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/daa172642b713076d7bdc7dd31b4c185cd3532ec

Thanks.

Luca Boccassi

Subject: [PATCH] net/ice/base: fix duplicate flow rules

[ upstream commit 43d30256b215937d9d8b554d39ac91f1866b0e5a ]

When a vsi that already exists in the created vsi_list subscribes to the
same filter again, the return value ICE_SUCCESS results in duplicate flow
rules to be stored, which will cause 'flush' and 'destroy' errors.

Fixes: fed0c5ca5f19 ("net/ice/base: support programming a new switch recipe")
