[dpdk-stable] patch 'app/eventdev: fix order test port creation' has been queued to LTS release 18.11.3

[Kevin Traynor <ktraynor@redhat.com>]

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 08/28/19. 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/0b6cf76cbd55261fd6a486c1c75ae668a7f4f4fd

Thanks.

Kevin Traynor

Subject: [PATCH] app/eventdev: fix order test port creation

[ upstream commit f77f8c9fe7ea2bd36e0bccd4c908c54e1b7f0420 ]

Configure event ports based on the underlying event device info rather
than using hardcoded values.

Fixes: 5710e751813e ("app/testeventdev: add order port setup")
