Subject: [PATCH net-next v1 4/7] net: phy: add PHY specifica flag to signal SmartEEE support

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.
