get_phy_id — reads the specified addr for its ID.
int get_phy_id ( | struct mii_bus * bus, |
| int addr, | |
| u32 * phy_id, | |
| bool is_c45, | |
struct phy_c45_device_ids * c45_ids); |
struct mii_bus * busthe target MII bus
int addrPHY address on the MII bus
u32 * phy_idwhere to store the ID retrieved.
bool is_c45If true the PHY uses the 802.3 clause 45 protocol
struct phy_c45_device_ids * c45_idswhere to store the c45 ID information.
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.
