[dpdk-stable] patch 'examples/flow_classify: fix NUMA check of port and core' has been queued to stable release 19.11.9

[Christian Ehrhardt <christian.ehrhardt@canonical.com>]

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:
https://github.com/cpaelzer/dpdk-stable-queue/commit/16632a29f39cfdac74d1b9556460160e0c8623df

Thanks.

Subject: [PATCH] examples/flow_classify: fix NUMA check of port and core

[ upstream commit 78a5545ef92b48553be4a244514a2514ca9b09b0 ]

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.

For example in flow_classify:
./build/flow_classify -a 0000:7d:00.1  -l 93
Here:
0000:7d:00.1 is on numa node 0.
core 93  is on numa node 3.

The two are not in same numa node, but no warning gives out in old codes
when device is on node 0.
This patch includes the node 0 in the check.

Fixes: bab16ddaf2c1 ("examples/flow_classify: add sample application")
