When the link status changes, the phylib calls the link_event function in the mvpp2 driver. Before this patch only the egress/ingress transmit was enabled/disabled. This patch adds more functionality to the link status management code by enabling/disabling the port per-cpu interrupts, and the port itself. The queues are now stopped as well, and the netif carrier helpers are called.
