Hi,

FYI, your patch has been queued to stable release 20.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/05/21. 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/ad67a31e0aa52d74cf6be335feff169c615dbfc0

Thanks.

Subject: [PATCH] net/iavf: fix Tx threshold check

[ upstream commit ed21e06e44ad7fe5dfa4b8ed713e29833a474fa9 ]

Function check_tx_thresh is called with wrong parameter. If the
check fails, tx_queue_setup should return error not keep going.
This patch fixes above issues.

Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
