Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/28/26. 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/6fe16055e3df0e5de13f09fc6d7e5da8150d03b0

Thanks.

Luca Boccassi

Subject: [PATCH] event/cnxk: fix crash on CN10K

[ upstream commit f181c1e2897eaf9defdabfcf9d641cf1b77436bf ]

The field evdev_priv will have valid event dev pointer only when
eth_rx_adapter_queue_add() is called.

In case of poll mode tests, queue add will not be called so this
will be NULL. It is fixed by having a NULL check before access.

Fixes: 01a990fe40e8 ("event/cnxk: fix OOP handling in event mode")
