Abstract
A system and method for tunneling control over a MAC/PHY interface for legacy ASIC support. Energy efficient Ethernet control or status information can be communicated over a MAC/PHY interface using control codes that are embedded in sequence ordered sets. These sequence ordered sets would not affect the data flow and can be tunneled within an existing interface (e.g., XAUI, XFI, xxMII or derivative interfaces) without generating errors.
