Subject: [net-2.6 PATCH 3/5] e1000e: io_error_detected callback should return
	PCI_ERS_RESULT_DISCONNECT

From: Mike Mason <mmlnx@...ibm.com>

on permanent failure

PCI drivers that implement the io_error_detected callback
should return PCI_ERS_RESULT_DISCONNECT if the state
passed in is pci_channel_io_perm_failure.  This state is not
checked in many of the network drivers.

This patch fixes the omission in the e1000e driver.
