Hi,

FYI, your patch has been queued to stable release 24.11.3

Note it hasn't been pushed to https://linkprotect.cudasvc.com/url?a=3Dhttp%3a%2f%2fdpdk.org%2fbrowse%2fdp= dk-stable&c=3DE,1,30w89yF4QLjfadAKGQFITCXmNAI8Fubd9zc_3CAyjRcyr7va20H2s= -pRwTp8SDIDMsUiJ7ia2x0VYw8GBCf30-aNCcdCSAH9ghwAa3liAemIg-mFdFHKuQKY13B1&= ;typo=3D1 yet.
It will be pushed if I get no objections before 07/23/25. 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 rebasi= ng
(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/co= mmit/cc5b54d0d2c07c676771ed09e74322f6512e6cc1

Thanks.

Kevin
