GET_PHY_ID(9)                         Network device support                        GET_PHY_ID(9)



NAME
       get_phy_id - reads the specified addr for its ID.

SYNOPSIS
       int get_phy_id(struct mii_bus * bus, int addr, u32 * phy_id, bool is_c45,
                      struct phy_c45_device_ids * c45_ids);

ARGUMENTS
       bus
           the target MII bus

       addr
           PHY address on the MII bus

       phy_id
           where to store the ID retrieved.

       is_c45
           If true the PHY uses the 802.3 clause 45 protocol

       c45_ids
           where to store the c45 ID information.

DESCRIPTION
       In the case of a 802.3-c22 PHY, reads the ID registers of the PHY at addr on the bus,
       stores it in phy_id and returns zero on success.

       In the case of a 802.3-c45 PHY, get_phy_c45_ids is invoked, and its return value is in
       turn returned.
