It makes this call: phydev = phy_connect(dev, phy_id, &adjust_link, 0, interface); where phy_id="24520:01". Using "24520:01:00" gets an error: eth0: 24520:01:00 already attached Maybe the DSA layer/driver needs to export a device "24520:01" which pretends all of the things that the gianfar wants (1000Mb/Full/Link)? -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
