[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/2a8b78ef483070ecff63c13daf2fa6c7628d4924

Thanks.

Luca Boccassi

Subject: [PATCH] net/dpaa: fix Rx queue shutdown before init

[ upstream commit ddb070d3c21e5e3b03f3c4ca749604420cdd3124 ]

The frame queue shutdown in dpaa_eth_rx_queue_setup() is too late:
the queue has already been created and initialized by dpaa_dev_init(),
so the shutdown forces a live FQ out of service and the queue no
longer receives frames.

Move the shutdown to dpaa_dev_init(), just before dpaa_rx_queue_init(),
where it cleans up a frame queue left over from a previous run as
intended.

Fixes: 0e3c389b9e4f ("bus/dpaa: do proper cleanup of frame queues on shutdown")
