[PATCH net-next v4 13/23] net: phy: add PHY specifica flag to signal SmartEEE support

From: Oleksij Rempel
Date: Wed Feb 01 2023 - 10:00:35 EST


Typical EEE support need cooperation of MAC and PHY, so both parts should
be able to do EEE. But, there also PHYs compatible with normal 802.3az
standard working with legacy MAC without EEE ability, acting as a complete
EEE power saving system.

To identify this PHYs we need a PHY specific flag. Since the PHY
specification implementing this functionality calls it SmartEEE, use
the same flag name - PHY_SMART_EEE.
