patch 'net/ice: write timestamp to first segment in scattered Rx' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. 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=52c903949a6c812ad124e6ddfec9a91c9bb2d552

Thanks.

Subject: [PATCH] net/ice: write timestamp to first segment in scattered Rx
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 6fc6b7260e0cd122433b4e439d7372a5281fff69 ]

Previously, the Rx timestamp was written to the last segment of the mbuf
chain, which was unexpected.

Fixes: 5543827fc6df ("net/ice: improve performance of Rx timestamp offload")
