Hi,
FYI, your patch has been queued to LTS release 18.11.3
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/19. 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-queue
This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/6676ee09c8bdd8aa3b731a17aa8fa02de2bdebee
Thanks.
