Will try to findout.

So please do add a PHY tunable via MAC driver. Yep, had the same thought. Will do. > Does the MAC also have the ability to configure PHY downshift? You > could implement that tunable as well. Right, its also possible and this is what I'm thinking on as well. This will require a minor change in ethtool infrastructure code to allow MAC driver to handle phy tunable requests. Regards, Igor
