title: ENETC external MDIO PCIe endpoint device
description:
NETC provides an external master MDIO interface (EMDIO) for managing external
devices (PHYs). EMDIO supports both Clause 22 and 45 protocols. And the EMDIO
provides a means for different software modules to share a single set of MDIO
signals to access their PHYs.
