> 
> This commit adds EEE (LPI) support indication for specific FEC Ethernet
> controllers. By indicating EEE support for these controllers, it allows PHY
> drivers to choose the right configuration for EEE and LPI features, depending
> on whether the MAC or the PHY is responsible for handling them.
> 
> This change provides more flexibility and control over energy-saving features,
> enabling PHY drivers to disable SmartEEE functionality in favor of MAC EEE
> support when appropriate, depending on their specific use cases and
> requirements.
