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:
https://github.com/bluca/dpdk-stable/commit/2091a78c0404ed4e5464559bb2a73978a30ca544

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

[ upstream commit 921ff14280ed8ba7b9d0a898046cf5eadf3d4c8e ]

Igc 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: a5aeb2b9e225 ("net/igc: support Rx and Tx")
