Subject: [PATCH net-next v2 3/8] net: phy: Add mac_supports_eee variable for EEE support and LPI handling
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.
