From 68707acb5b5d4e2b7583cbff0883516afed54d4f Mon Sep 17 00:00:00 2001 From: Bill Hayes Date: Tue, 19 Feb 2008 10:24:41 -0800 Subject: igb: Fix panic with NICs with 1000BASE-SX PHY This patch eliminates a kernel panic with the igb driver in 2.6.25-rc2 when running on a Intel 82575 Ethernet controller with a 1000BASE-SX PHY. The panic does not happen with the 1000BASE-T PHY, only with a SX connection.
