[dpdk-stable] patch 'usertools: fix telemetry client with python 3' has been queued to LTS release 18.11.7

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/25/20. 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/412970816782faf3eedcf407482225dd70b7b856

Thanks.

Kevin.

Subject: [PATCH] usertools: fix telemetry client with python 3

[ upstream commit af927da4d7d23f1050f23caf55f4ac2a995ab244 ]

The client script for use with the telemetry library did not support
Python3, as the data being sent over the socket was in string format.
Python3 requires the data be explicitly converted to bytes before being
sent. Similarly, the received bytes need to be decoded into string
format.

Fixes: 53f293c9a783 ("usertools: replace unsafe input function")
Fixes: fe35622659ed ("usertools: fix telemetry client with python 3")
Fixes: d1b94da4a4e0 ("usertools: add client script for telemetry")
Fixes: 4080e46c8078 ("telemetry: support global metrics")
