[PATCH net-next v2 2/8] net: phy: add is_smart_eee_phy variable for SmartEEE support

[Oleksij Rempel]

This commit introduces a new variable, is_smart_eee_phy, to the PHY
layer. This variable is used to indicate whether a PHY supports the
SmartEEE functionality, which is a Low Power Idle (LPI) implementation
on the PHY side, typically handled by the MAC.

By adding the is_smart_eee_phy variable, PHY drivers and the PHYlib
framework can provide proper configuration depending on the side that
implements LPI (PHY or MAC).
