[dpdk-stable] patch 'net/netvsc: fix probe when VF not found' has been queued to LTS release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 01/11/19. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] net/netvsc: fix probe when VF not found

[ upstream commit f2b76d22f85694864bbcd0f88267de9ef02d75c0 ]

It is possible that the VF device exists but DPDK doesn't know
about it. This could happen if device was blacklisted or more
likely the necessary device (Mellanox) was not part of the DPDK
configuration.

In either case, the right thing to do is just keep working
but only with the slower para-virtual device.

Fixes: dc7680e8597c ("net/netvsc: support integrated VF")
