Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:

Subject: [PATCH] net/virtio: fix getting old status on reconnect

[ upstream commit 721dbeb329fe3a26ec95e93f1877ec3f7184eaae ]

This patch fixes getting reset status from the restarted
vhost-user backend in case of reconnection, instead of the
status at the time of the disconnection.

This issue was not spotted earlier because Vhost-user
protocol status feature was disabled in server mode.

Fixes: 47235f16505f ("net/virtio-user: set status on socket reconnect")
