patch 'net/mana: check vendor ID when probing RDMA device' has been queued to stable release 23.11.5

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/28/25. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=2e2c96c0385d790636c1adee23c938ac5ad01200

Thanks.

Subject: [PATCH] net/mana: check vendor ID when probing RDMA device
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit be4ed96378811e572860cac558bff54b5c361992 ]

The RDMA kernel driver may expose two MANA RDMA devices, for RC and RAW
QP types. The purpose is to support fast service mode at SOC. Depending
on kernel version, the probe may fail if DPDK picks up the wrong device.

Add check for vendor_part_id and RAW QP capability when probing the MANA
device. This check is compatible with all kernel versions.

Fixes: 517ed6e2d590 ("net/mana: add basic driver with build environment")
