13 bus
14 the target MII bus
15
16 addr
17 PHY address on the MII bus
18
19 phy_id
20 where to store the ID retrieved.
21
22 is_c45
23 If true the PHY uses the 802.3 clause 45 protocol
24
25 c45_ids
26 where to store the c45 ID information.
27
29 In the case of a 802.3-c22 PHY, reads the ID registers of the PHY at
30 addr on the bus, stores it in phy_id and returns zero on success.
31
32 In the case of a 802.3-c45 PHY, get_phy_c45_ids is invoked, and its
33 return value is in turn returned.
