[dpdk-stable] patch 'event/dsw: ignore scheduling type for single-link queues' 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 05/20/19. 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/c8a8ccd7f1bfbe2696be4dbdb967aa4e4f65f3ce

Thanks.

Kevin Traynor

[ upstream commit 7e192bdb0c55745a81e7f5e0eaf2b7a911aeadd4 ]

The scheduling type parameter is not applicable for single link
queues. DSW would, at the time of rte_event_queue_setup(), erroneously
verify that scheduling type was one of the supported types, and
returned -ENOTSUP in case of RTE_SCHED_TYPE_ORDERED.

Fixes: 4540ee9c68 ("event/dsw: add device and queue configuration")
