Hi,

FYI, your patch has been queued to stable release 20.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/23/22. 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/steevenlee/dpdk

This queued commit can be viewed at:

Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 5d4a6a437076c3ba6230a36b1d811ab69272fab6 ]

Since QEMU 5.2.0 fixes the vhost split ring multi-queue reconnection
issue in commit f66337bdbfda ("vhost-user: save features of multiqueues
if chardev is closed"), this patch updates known issue to indicate
the range of affeacted QEMU versions.

Fixes: b37e95507e1b ("doc: add vhost multi-queue reconnection issue")

 **Description**
    It's a QEMU regression bug (bad commit: c6beefd674ff). QEMU only saves

 **Implication**
    Vhost cannot reconnect back to virtio-net/virtio-pmd normally.
