[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/25/24. 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/b4daf0e0fd6a71a3a72646ac72434e86d9cfad54

Thanks.

Luca Boccassi

Subject: [PATCH] net/dpaa: fix typecasting channel ID

[ upstream commit 5edc61ee9a2c1e1d9c8b75faac4b61de7111c34e ]

Avoid typecasting ch_id to u32 and passing it to another API since it
can corrupt other data. Instead, create new u32 variable and typecast
it back to u16 after it gets updated by the API.

Fixes: 0c504f6950b6 ("net/dpaa: support push mode")
