patch 'net/virtio: fix Rx and Tx queue state' has been queued to stable release 21.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/08/23. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/a508510366ea6eed6e2b74a6177ccb142b34e8ce

Thanks.

Kevin

Subject: [PATCH] net/virtio: fix Rx and Tx queue state

[ upstream commit 0170be6f4f90fdf3295c23520fc1547c1a2405db ]

The DPDK framework reports the queue state, which is stored in
dev->data->tx_queue_state and dev->data->rx_queue_state. The
state is maintained by the driver. Users may determine whether
a queue participates in packet forwarding based on the state.
Therefore, the driver needs to modify the queue state in time
according to the actual situation.

Fixes: 9ad9ff476cac ("ethdev: add queue state in queried queue information")
