patch 'net/hns3: fix outer UDP checksum with simple BD' has been queued to stable release 24.11.5

Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/22/26. 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/0832e61db4818ed1f7486a0c51ad10df76f787b1

Thanks.

Luca Boccassi

Subject: [PATCH] net/hns3: fix outer UDP checksum with simple BD

[ upstream commit dce76acf61859242946e619cf6113de5e134b117 ]

On the hardware platform that supports simple BD, if outer-ip, outer-udp
and udp checksum offloading are enabled, the hardware incorrectly
processes the ether+ipv6+vxlan+ether+ipv4+udp packet (the incorrect
field is modified).

The root cause is that the simple BD feature does not exclude outer-udp
checksum. This commit add it.

Fixes: 6393fc0b823c ("net/hns3: simplify hardware checksum offloading")
