This commit introduces a new variable, mac_supports_eee, to the PHY layer. This variable is used to indicate if a MAC provides EEE support or is responsible for Low Power Idle (LPI) handling. The mac_supports_eee variable should be used in conjunction with is_smart_eee_phy to make proper configuration decisions based on the capabilities of both the PHY and MAC. By adding the mac_supports_eee variable, PHY drivers and the PHYlib framework can better coordinate EEE and LPI management between the PHY and MAC.
