patch 'net/mlx5: prevent ioctl failure log flooding' has been queued to stable release 21.11.7

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/09/24. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/eadfb0fbb89359dcd3e846ab88a6988a1c69f61d

Thanks.

Kevin

Subject: [PATCH] net/mlx5: prevent ioctl failure log flooding

[ upstream commit 84ba1440c5dff8d716c1a2643aa3eb5e806619ff ]

The following log is printed in WARNING severity:

mlx5_net: port 1 ioctl(SIOCETHTOOL, ETHTOOL_GPAUSEPARAM) failed:
    Operation not supported

Reduce the severity to DEBUG to prevent this log from flooding
when there are hundreds of ports probed without supporting this
flow ctrl query.

Fixes: 1256805dd54d ("net/mlx5: move Linux-specific functions")
