Hi,

FYI, your patch has been queued to stable release 20.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/22/23. 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/bluca/dpdk-stable

This queued commit can be viewed at:

Subject: [PATCH] net/ixgbe: fix Rx and Tx queue status

[ upstream commit 4a8490075692c32797be4280aea33772a5865038 ]

Ixgbevf driver don't enable queue start/stop functions, queue status is not
updated when the HW queue enabled or disabled. It caused application can't
get correct queue status.
This patch fixes the issue by updating the queue states when the queue is
disabled or enabled.

Fixes: 429c6d86b371 ("ixgbe: prepare for vector pmd")
Fixes: f0c50e5f56fa ("ixgbe: move PMD specific fields out of base driver")
