Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/47e1440e2e9ee47b3b74d835f43a71fd7c93a357

Thanks.

Luca Boccassi

Subject: [PATCH] doc: fix some statements for ice vector PMD

[ upstream commit c2e129698dd6c03a598be3084abffb38ab0c801c ]

1. Add descriptions for how to select avx512 datapath.
2. Add explanation for "P" in ice.ini.

Fixes: 7f85d5ebcfe1 ("net/ice: add AVX512 vector path")
Fixes: 271cc8c5028a ("doc: update ice features list")
