Hi,

FYI, your patch has been queued to stable release 22.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/14/24. 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://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/58d7a7a993b52b5120205cbada4f0d0c2173af9a

Thanks.

Luca Boccassi

[ upstream commit 0c5709824b531e83b36ed91852cea98b1cb292e1 ]

Allowing ring memory allocation whose end address is aligned with 64 MB.
Previous logic was off by one.
