For example, Marvell PHYs are designed to have EEE hardware disabled during the initial state, and it needs to be configured to turn it on again. This patch reads the PHY configuration and sets it as the initial value for eee_cfg.tx_lpi_enabled and eee_cfg.eee_enabled instead of having them set to true by default.
