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.
