Abstract
In one embodiment, a modified local PHY is adapted to couple a legacy host device to link partner implementing Energy Efficient Ethernet. The modified local PHY includes a buffer and if the legacy host transmits data when the modified local PHY is in a Low Power Idle (LPI) state then the data is stored in the buffer and transmission is paused until the modified local PHY transitions from the LPI state to an active state.
