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 07/14/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/da7d8b7da30754d7a69d76f0cf7da8f6a6ee8ce0

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: set flow error when free filter not available

[ upstream commit 94df7953ac6599c2887b859de19c541e5b5830d9 ]

In bnxt_flow_validate(), when bnxt_get_unused_filter() fails due to
no filter resources available, driver is not setting flow error using
"rte_flow_error_set".

Also, fixed the error code.

Fixes: 5ef3b79fdfe6 ("net/bnxt: support flow filter ops")
