[dpdk-stable] patch 'power: rename constants' has been queued to stable release 19.11.7

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

Hi,

FYI, your patch has been queued to stable release 19.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/06/21. 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/b9f75f2721aeac4d1fa7962d2aa89feaa66b64c5

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] power: rename constants

[ upstream commit 38d232b9b804eebd458d758f2face173220ee2f8 ]

Rename the #defines to have an RTE_POWER_ prefix

Fixes: 210c383e247b ("power: packet format for vm power management")
Fixes: cd0d5547e873 ("power: vm communication channels in guest")
