.SH "DESCRIPTION"
.PP
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\&.
