patch 'net/gve: fix RSS hash endianness in DQO format' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/14/24. 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://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=c90d304f0eed545d8f7ec36ceacf04778c856a7c

Thanks.

Subject: [PATCH] net/gve: fix RSS hash endianness in DQO format
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit b0ab5e931135664a554e0fd1e28fe11ee73f4463 ]

The hash field in struct gve_rx_compl_desc_dqo defined in
gve_desc_dqo.h has the type __le32. Therefore the hash must be
read in little endian rather than big endian.

Bugzilla ID: 1441
Fixes: 45da16b5b181 ("net/gve: support basic Rx data path for DQO")
