[PATCH] net/mlx5: prevent ioctl failure log from flood

[PATCH] net/mlx5: prevent ioctl failure log from flood

[Bing Zhao]

From: Eli Britstein <elibr@nvidia.com>

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")
