patch 'net/bonding: fix dedicated queue setup' has been queued to stable release 24.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/17/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/f47b48eff78e68d006a2db292c0293f93f8ba3e3

Thanks.

Kevin

Subject: [PATCH] net/bonding: fix dedicated queue setup

[ upstream commit 4da0705bf896327af062212b5a1e6cb1f1366aa5 ]

The bonding PMD hardcoded the value of dedicated hardware Rx/Tx
queue size as (128/512). This will cause the bonding port start
fail if some NIC requires more Rx/Tx descriptors than the hardcoded
number.

Therefore, use the minimum hardware queue size of the member port
to initialize dedicated hardware Rx/Tx queue. If obtaining the
minimum queue size failed, use the default queue size.

Fixes: 112891cd27e5 ("net/bonding: add dedicated HW queues for LACP control")
