[dpdk-stable] patch 'bus/vmbus: fix secondary process setup' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/01/19. 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 can be viewed on the 18.11 branch at:
	https://github.com/kevintraynor/dpdk-stable-queue.git

Thanks.

Kevin Traynor

Subject: [PATCH] bus/vmbus: fix secondary process setup

[ upstream commit fc20b5809dbc7ee8a341ec5db166de5a51d7118a ]

The secondary process doesn't correctly map the second
and later resources because it doesn't change the offset.

Fixes: 831dba47bd36 ("bus/vmbus: add Hyper-V virtual bus support")
