From a59e8a1a72806057084adc2d321fc2a7cbce9579 Mon Sep 17 00:00:00 2001 From: Emil Tantilov Date: Thu, 31 Mar 2011 09:36:12 +0000 Subject: [PATCH] ixgbe: explicitly disable 100H for x540 100H is not supported on this HW, but the bit is set on the PHY. This can result in link at 100F when advertising only 1000F.
