It will be pushed if I get no objections before 06/03/20. 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/kevintraynor/dpdk-stable-queue This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable-queue/commit/b622d8c04eac87376d0d2b366404517e7cc90f5f Thanks.

It has to be in rte_malloc'd memory or a message will be printed on shutdown/close.
