Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/21/25. 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/ad8a7ddf129931efaebb971ea92d275f0f0728d5

Thanks.

Luca Boccassi

Subject: [PATCH] net/iavf: fix crash on app exit on FreeBSD

[ upstream commit 44a86bcf2447d7d914d7195448285aa82eaedcba ]

With the fallback interrupt path now enabled on FreeBSD there are
segmentation faults on app exit, due to the alarm interrupt trying to
access invalid pointers.  Add checks for null to fix these crashes.

Fixes: cd3b124955d4 ("net/iavf: enable interrupt polling")
