Hi,

FYI, your patch has been queued to stable release 22.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/02/25. 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/4f11c905afb974890cbce23bb90e8a9114971317

Thanks.

Luca Boccassi

Subject: [PATCH] event/dlb2: fix default credits based on HW version

[ upstream commit 07a08b13b3bc65abe295557d1dc2609e7f4afc45 ]

dlb2_eventdev_info_get() that implements rte_event_dev_info_get() should
return the maximum available credits as supported by HW.

Set maximum credits before device probing by checking HW version.

Fixes: b66a418d2ad3 ("event/dlb2: add v2.5 probe")
