From c93b5a76d58656158d195a7df507ebc660010969 Mon Sep 17 00:00:00 2001 From: Mike Mason Date: Tue, 30 Jun 2009 12:45:53 +0000 Subject: [PATCH] e1000e: io_error_detected callback should return PCI_ERS_RESULT_DISCONNECT 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. Signed-off-by: Mike Mason Signed-off-by: Jeff Kirsher Signed-off-by: David S.
