[dpdk-stable] patch 'net/netvsc: initialize link state' has been queued to stable release 19.11.1

[luca.boccassi at gmail.com]

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 02/19/20. 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/netvsc: initialize link state

[ upstream commit 047ad3787a2f5d99277e0d8d756580a1d5ea2891 ]

If application is using link state interrupt, the correct link state
needs to be filled in when device is started. This is similar to
how virtio updates link information.

Fixes: 4e9c73e96e83 ("net/netvsc: add Hyper-V network device")
