patch 'net/ice: fix tunnel packet Tx descriptor' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/11/23. 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=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=c8b6f57dc4476ffbada1d3051c2c57680ca1018f

Thanks.

Subject: [PATCH] net/ice: fix tunnel packet Tx descriptor
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit c261e7de45d38ddc3b4b8909c35b448c5e1b0fcf ]

The TX descriptor of tunnel packet filled incorrectly due to the MACLEN
is not set.

This patch fixes this issue by setting MACLEN to correctly fill the
TX descriptor.

Fixes: bd70c451532c ("net/ice: support Tx checksum offload for tunnel")
