NAME
       phy_prepare_link - prepares the PHY layer to monitor link status

SYNOPSIS
       void phy_prepare_link(struct phy_device * phydev, void (*handler) (struct net_device *));

ARGUMENTS
       phydev
	   target phy_device struct

       handler
	   callback function for link status change notifications

DESCRIPTION
       Tells the PHY infrastructure to handle the gory details on monitoring link status (whether through polling or an interrupt), and to call
       back to the connected device driver when the link status changes. If you want to monitor your own link state, don't call this function.
