A method and apparatus for enabling low power idle (LPI) signaling for Ethernet transceivers operating in legacy modes are disclosed that allow a high speed transceiver to retain energy efficient Ethernet (EEE) functionality even when the transceiver is operating in a slower speed mode. In some embodiments, an Ethernet device may enter an LPI mode upon receiving a regular LPI signal when its media independent interface (MII) is operating at a first transmission rate, and may enter the LPI mode upon receiving a modified LPI signal when the MII is operating at a first speed operating at a second transmission rate that is slower than the first transmission rate. |
