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.
