It will be pushed if I get no objections before 12/10/19. 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 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-queue This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable-queue/commit/b2bfe186b0770637d2= fdff4f5357bce8950b816c Thanks.
