[dpdk-stable] patch 'app/eventdev: remove redundant enqueue in burst Tx' has been queued to stable release 19.11.7

[Christian Ehrhardt]

Hi,

FYI, your patch has been queued to stable release 19.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/06/21. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/3a6a49cdc667a13176a76218ba72ea11cf1e5ff9

Thanks.

Subject: [PATCH] app/eventdev: remove redundant enqueue in burst Tx

[ upstream commit 21b1ca4843a09d822cf992872445beb73163f1fb ]

For eventdev pipeline test, in burst_tx cases, there is no needed to
set ev.op as RTE_EVENT_OP_RELEASE and call pipeline_event_enqueue_burst
to release events. This is because for tx mode(internal_port=true),
the capability "implicit_release" of dev is enabled, and the app can
release events by "rte_event_dequeue_burst" rather than enqueue.

Fixes: 314bcf58ca8f ("app/eventdev: add pipeline queue worker functions")
