[dpdk-stable] patch 'event/sw: fix enqueue checks in self-test' has been queued to LTS release 18.11.2

[Kevin Traynor]

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 05/01/19. 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 the 18.11 branch at:
	https://github.com/kevintraynor/dpdk-stable-queue.git

Thanks.

Kevin Traynor

Subject: [PATCH] event/sw: fix enqueue checks in self-test

[ upstream commit 1b03e2929114d4ebfc7a2159d0d45f0a3e9a7ba6 ]

This patch fixes a number of instances of the same return
value mis-check, where previously we checked for a negative
return value as error, however the API returns an unsigned
integer, so these return value checks are invalid.

The rte_event_enqueue_burst() API returns the number of
events enqueued, so in order to identify the error case,
we must check for != the number of intended enqueues.

Fixes: cd1a9e3eab55 ("test/eventdev: add SW tests for load balancing")
