Reads the specified addr for its 802.3-c45 ids.
int get_phy_c45_ids(struct mii_bus * bus, int addr, u32 * phy_id, struct phy_c45_device_ids * c45_ids);
bus
the target MII bus
addr
PHY address on the MII bus
phy_id
where to store the ID retrieved.
c45_ids
where to store the c45 ID information.
If the PHY devices-in-package appears to be valid, it and the corresponding identifiers are stored in c45_ids, zero is stored in phy_id. Otherwise 0xffffffff is stored in phy_id. Returns zero on success.
