+ * The function sets default EEE policy parameters, including preparing the PHY
+ * to advertise EEE capabilities based on hardware support.
+ *
+ * It also sets the expected configuration for Low Power Idle (LPI) in the MAC
+ * driver. If the PHY framework determines that both local and remote
+ * advertisements support EEE, and the negotiated link mode is compatible with
+ * EEE, it will set enable_tx_lpi = true. The MAC driver is expected to act on
