Abstract

A system and method for enabling legacy media access control (MAC) to do energy efficient Ethernet (EEE). A backpressure mechanism is included in an EEE enhanced PHY that is responsive to a detected need to transition between various power modes of the EEE enhanced PHY. Through the backpressure mechanism, the EEE enhanced PHY can indicate to the legacy MAC that transmission of data is to be deferred due to a power savings initiative in the EEE enhanced PHY.
