[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/11/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=1622bab08e5c565d3fda6b0a57176b649c96ff54

[ upstream commit b2a0271188f3428ad5dc1ea600e1e2254b9d6781 ]

Igb 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: be2d648a2dd3 ("igb: add PF support")
