7title: ENETC external MDIO PCIe endpoint device
8
9description:
10 NETC provides an external master MDIO interface (EMDIO) for managing external
11 devices (PHYs). EMDIO supports both Clause 22 and 45 protocols. And the EMDIO
12 provides a means for different software modules to share a single set of MDIO
13 signals to access their PHYs.
