Hi Igor

Can you point to some section of the PHY datasheet? I could not find
anything which fit the vague description you have of this feature in
your patch. Maybe Heiner or I can implement and verify the PHY driver
using this feature.

Since this feature can be implemented directly in the PHY driver, and
indirectly via the MAC in firmware, it would be good to have a uniform
interface to do this. So please do add a PHY tunable via MAC driver.

Does the MAC also have the ability to configure PHY downshift? You
could implement that tunable as well.
