Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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/692ae335d6040a91682057543a927903f57d0fb4

Thanks.

Kevin

Subject: [PATCH] eventdev/eth_tx: fix queue add error code

[ upstream commit bd0a32d14b87661c39130d73ab4323247b80f864 ]

The internal function txa_service_queue_add() is returning 0
in case of error, correct this logic to return a negative value
to indicate failure.

Fixes: a3bbf2e09756 ("eventdev: add eth Tx adapter implementation")
