Hi,

FYI, your patch has been queued to stable release 20.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/31/23. 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/f93f785d060077a584e15c85cc29ac20a4510ded

Thanks.

Luca Boccassi

Subject: [PATCH] net/mlx5: fix CQE dump for Tx

[ upstream commit cd4158177434d557742b4bb0fbe68e59d2c2db21 ]

The regular CQE size can be 64 bytes or 128 bytes depending
on the cache line size. The error CQE is always 64 bytes long.
Only 64 bytes are dumped to the log file in case of Tx queue
recovery form the error. Use the CQE size, not the error CQE size.

Fixes: 957e45fb7bcb ("net/mlx5: handle Tx completion with error")
