patch 'common/cnxk: fix mbuf data offset for VF' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/14/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/c22759e121fb0d1cf8c3ea3b67e3616289c4066e

Thanks.

Kevin

Subject: [PATCH] common/cnxk: fix mbuf data offset for VF

[ upstream commit 8f98e3ecc55e02234f8bec7213b0b6a69c086949 ]

If PF has PTP enabled the data offset should be adjusted for VF to
skip extra 8 bytes of timestamp as the MAC inserts 8 bytes before
the ethernet header.

Fixes: c443e0d326e1 ("common/cnxk: support NIX PTP")
