Overview
The mdio driver provides an interconnection between the Media Access Control (MAC) sublayer and Physical Layer (PHY) entities' control and status registers, as defined by the IEEE 802.3 Standard.
The mdio layer allows device drivers to share common support code for various external PHY devices.
MDIO is one of two signal interfaces that comprise the Media Independent Interface (MII) defined by the IEEE 802.3 Standard. The miibus(4) driver provides support for devices that require full MII support.
