[dpdk-stable] patch 'test/event: fix timeout accuracy' has been queued to stable release 19.11.9

[Christian Ehrhardt]

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/19/21. 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/e60e641b3b8beb4ba531954c38c5e0cb0226dd84

Subject: [PATCH] test/event: fix timeout accuracy

[ upstream commit 41f27795bb947c9aa1d02e0c8a2688af2a3197ba ]

Round timeout ticks when converting from nanoseconds, this prevents
loss of accuracy and deviation from requested timeout value.

Fixes: d1f3385d0076 ("test: add event timer adapter auto-test")
