From f55744adeee8598a05f0714b8fe9d131865ef060 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Wed, 30 Aug 2017 10:29:17 +0200 Subject: [PATCH] net: mvpp2: improve the link management function 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. Signed-off-by: Antoine Tenart Signed-off-by: David S.
