-Subject: [PATCH 714/744] phy: provide a hook for link up/link down events
-
-Sometimes, we need to do additional work between the PHY coming up and
-marking the carrier present - for example, we may need to wait for the
-PHY to MAC link to finish negotiation.  This changes phylib to provide
-a notification function pointer which avoids the built-in
-netif_carrier_on() and netif_carrier_off() functions.
-
-Standard ->adjust_link functionality is provided by hooking a helper
-into the new ->phy_link_change method.
