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 06/14/25. 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/34a9e04b4743b066c45183c93fc3024dea16dda5

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: fix integer overflow in interrupt unmap

[ upstream commit e401c04481c7a6a4199504d6f4696c48620ff093 ]

The number of interrupt vector may exceed the range of uint8_t.
So hns3_unmap_rx_interrupt() should use uint16_t for 'vec' variable.

Fixes: 02a7b55657b2 ("net/hns3: support Rx interrupt")
