int phy_attach_direct(struct net_device *  dev , struct phy_device *  phydev , u32  flags , phy_interface_t  interface );

dev
    network device to attach

phydev
    Pointer to phy_device to attach

flags
    PHY deviceAqs dev_flags

interface
    PHY deviceAqs interface

Called by drivers to attach to a particular PHY device. The phy_device is found, and properly hooked up to the phy_driver. If no driver is attached, then the genphy_driver is used. The phy_device is given a ptr to the attaching device, and given a callback for link status change. The phy_device is returned to the attaching driver.
