[dpdk-stable] patch 'app/testpmd: fix stdout flush after printing stats' 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 04/24/19. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] app/testpmd: fix stdout flush after printing stats

[ upstream commit 683d1e82a0f2caae1a9c6f1209ab4d743373a173 ]

User can specify stats period(n). The statistics should be available
to user every n second. But the print_stats() function does not
force stdout to be flushed, so for instance, a user reading testpmd's
stdout through pipe will not be able to read it until the stdout
buffer is filled.

Fixes: cfea1f3048d1 ("app/testpmd: print statistics periodically")
