Hi,

FYI, your patch has been queued to stable release 22.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/09/24. 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/8dd3b5b4abc62c68619d4e8545f5fc5a421afc5c

Thanks.

Luca Boccassi

Subject: [PATCH] event/cnxk: fix dequeue timeout configuration

[ upstream commit efcf81e1a89fa7b20aae17accfcb4a8e7ddc3d02 ]

Allow dequeue timeout to be configured as zero, when
RTE_EVENT_DEV_CFG_PER_DEQUEUE_TIMEOUT is disabled.

Fixes: 5512c7de85cd ("event/cnxk: add common configuration validation")
