Subject: [PATCH net 4/5] net/mlx5e: Don't print error message due to invalid module

From: Gal Pressman <gal@...dia.com>

Dumping module EEPROM on newer modules is supported through the netlink
interface only.

Querying with old userspace ethtool (or other tools, such as 'lshw')
which still uses the ioctl interface results in an error message that
could flood dmesg (in addition to the expected error return value).
The original message was added under the assumption that the driver
should be able to handle all module types, but now that such flows are
easily triggered from userspace, it doesn't serve its purpose.

Change the log level of the print in mlx5_query_module_eeprom() to
debug.
