From 9f0b8516198e8b0919774a1874fab064a2ea3ae8 Mon Sep 17 00:00:00 2001 From: Matthew Vick Date: Tue, 16 Oct 2012 07:44:45 +0000 Subject: igb: Enable auto-crossover during forced operation on 82580 and above. Newer devices supported by igb can support auto-crossover detection in forced operation modes. Enable this in the driver, rather than clobbering this functionality in forced operation.
