[dpdk-stable] patch 'test: fix autotest crash' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/19. 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 are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/08385dc344141eccac5ebea8a8782a373109774a

Thanks.

Kevin Traynor

Subject: [PATCH] test: fix autotest crash

[ upstream commit c6ad35c468451466720009b374c9b19c43b9f7ae ]

On some systems when dpdk test is executed with make test command
autotest_runner crashes in first_cpu_on_node. This happens when list
of available cpus contains something that is not a cpu as first element.
Fixed by removing all non-cpu values from list of available cpus.

Bugzilla ID: 253
Fixes: 22dcd9a4d90f ("test: parallelize unit tests")
