[dpdk-stable] patch 'examples/skeleton: fix NUMA check of port and core' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/acf64e968541c95f31185d09d537639b4e647ff9

Thanks.

Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 5ffa60cd77c76855690d06cb900d6670f29de9a6 ]

According to the comments and logging, the author just hope user to use
the core and device which are in the same numa node for optimal
performance. If not, A warning gives out.

This patch fixes the check for a device on the node 0.

Fixes: 7107e471a6c7 ("examples/skeleton: very simple code for packet forwarding")
