MDIOBUS_SCAN(9)                       Network device support                      MDIOBUS_SCAN(9)



NAME
       mdiobus_scan - scan a bus for MDIO devices.

SYNOPSIS
       struct phy_device * mdiobus_scan(struct mii_bus * bus, int addr);

ARGUMENTS
       bus
           mii_bus to scan

       addr
           address on bus to scan

DESCRIPTION
       This function scans the MDIO bus, looking for devices which can be identified using a
       vendor/product ID in registers 2 and 3. Not all MDIO devices have such registers, but PHY
       devices typically do. Hence this function assumes anything found is a PHY, or can be
       treated as a PHY. Other MDIO devices, such as switches, will probably not be found during
       the scan.
