Subject: [net-next-2.6 PATCH 4/5] ixgbe: Return PCI_ERS_RESULT_DISCONNECT when
	bus is disabled

From: Breno Leitao <leitao@...ux.vnet.ibm.com>

According to the "PCI Error Recovery" document, if after a recovery,
the bus is disabled, the error_detected function should return
PCI_ERS_RESULT_DISCONNECT. Actually ixgbe error_detected function is
always returning PCI_ERS_RESULT_NEED_RESET, even if the bus is in failure.
This patch just check if the bus is disabled and then returns
PCI_ERS_RESULT_DISCONNET.
