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 06/13/26. 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/97a78a6557a75a05307a98d2f1d34a2e2c53c018

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: fix QP resource count in backing store config

[ upstream commit ae9b86e7dc3b7d71279f9746ebc6611caed23af3 ]

The driver is not passing the QP1 count while
configuring backing store for QP type.
This can result in a smaller set of entries allocated by the
driver with the firmware.

The number of entries is provided by the firmware as a
part of backing store qcaps v2 HWRM command.

Fixes: fe2f715ca580 ("net/bnxt: support backing store v2")
