ixgb: return PCI_ERS_RESULT_DISCONNECT on permanent failure
PCI drivers that implement the struct pci_error_handlers' error_detected callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is pci_channel_io_perm_failure. This patch fixes the issue for ixgb. Signed-off-by: Dean Nelson <dnelson@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
