Management Data Input or Output (MDIO) is a control protocol designed primarily for use with ethernet PHY devices. It typically utilizes an unidirectional 2.5 MHz clock signal (MDC) and bidirectional data bus line (MDIO). See Translate Voltage for RGMII for details on the accompanying RGMII translation.
