[dpdk-stable] patch 'app/testpmd: fix mempool free on exit' has been queued to LTS release 18.11.2

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/07/19. 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 can be viewed on a temporary branch at:
	https://github.com/kevintraynor/dpdk-stable-queue.git

Thanks.

Kevin Traynor

[ upstream commit 401b744da2cf0f87991127e5b422cde6cde3d726 ]

Allocated mempools were never free. it is bad practice.
