It will be pushed if I get no objections before 11/11/20. 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/d08a94deae48b03553538bbb8d6b44323c4ee304 Thanks.
