Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/57fa44d585937d74c18444fa81612c1fe3c7867d

Thanks.

Luca Boccassi

Subject: [PATCH] net: fix VLAN insert doc for shared-mbuf error code

[ upstream commit 3ffabed4ba32d4d999759630a23053bcec796b9f ]

The implementation returns -EINVAL when the mbuf is shared or
indirect, but the doc comment inaccurately stated -EPERM.

Fixes: c974021a5949 ("ether: add soft vlan encap/decap")
