Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/15/26. 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/a252962d48439c24376bc05a53f4cdd7acde5471

Thanks.

Subject: [PATCH] net/dpaa2: fix Rx queue count for primary process

[ upstream commit 0800fa6e31e28e734815197360f3533e70d2f000 ]

The rx_queue_count callback was only assigned on the secondary process
path of dpaa2_dev_init(), leaving eth_dev->rx_queue_count NULL for the
primary process. The fast-path rte_eth_rx_queue_count() performs an
unguarded indirect call in non-debug builds, so invoking it on a
primary-process dpaa2 port dereferences a NULL function pointer and
crashes.

Assign the callback on the primary-process path as well, so both the
primary and secondary paths set it.

Fixes: cbfc6111b557 ("ethdev: move inline device operations")
