[dpdk-stable] patch 'net/vhost: check creation failure' has been queued to stable release 19.11.1

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/13/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/vhost: check creation failure

[ upstream commit f04513bc89d90c2ad425f1be1e4716bb3c790fb2 ]

The function eth_dev_vhost_create() could return errors,
the return value need to be checked.

Fixes: ee584e9710b9 ("vhost: add driver on top of the library")
