[dpdk-stable] patch 'examples/l2fwd-cat: fix NUMA check of port and core' 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 06/12/21. 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:

Subject: [PATCH] examples/l2fwd-cat: fix NUMA check of port and core

[ upstream commit 59a50c6a9ace0dc736d71e75267a1cc2127e7938 ]

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: f6baccbc2b3b ("examples/l2fwd-cat: add sample application for PQoS CAT and CDP")
