[dpdk-stable] patch 'app/testpmd: fix quit to stop all ports before close' has been queued to LTS release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/19. 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 quit to stop all ports before close

[ upstream commit 08fd782b8454ab9019290d35f4e5334b4235923e ]

This patch proposes a slightly different test-pmd quit operation: stop
all devices before starting to close any device. Basically, stop all
moving parts before beginning to remove them. The current test-pmd quit
is stopping and closing each device before moving to the next device.

If all devices in the system are independent of each other, this
difference is usually not important. In case of Soft NIC devices, any
such virtual device typically depends on one or more physical devices
being alive, as it accesses their queues, so this difference becomes
important.

Without this straightforward fix, all the Soft NIC devices need to be
manually stopped before the quit command is issued, otherwise the quit
command can sometimes crash the test-pmd application.

Fixes: d3a274ce9dee ("app/testpmd: handle SIGINT and SIGTERM")
