patch 'mbuf: fix dynamic fields copy' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/14/24. 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=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=c9071e44b74503d54963e65a91ff9c57d3fc2251

Thanks.

[ upstream commit 95bea772528d316c969a170e6206f3b05ac39413 ]

Fixed rte_mbuf_dynfield_copy() API to copy dynamic fields from one mbuf
to another. When RTE_IOVA_AS_PA is not defined during the build, an
additional dynamic field (dynfield2) becomes available. This field
should be conditionally copied to ensure the complete duplication of
dynamic fields between mbufs. This patch fixes the same.

Bugzilla ID: 1472
Fixes: 03b57eb7ab9a ("mbuf: add second dynamic field member")
