From: Mike Christie <michaelc@xxxxxxxxxxx> This has qla2xxx use the new transport error values instead of DID_BUS_BUSY. I am not sure if all the errors in qla_isr.c I changed are transport related. We end up blocking/deleting the rport for all of them so it is ok to use the new transport error since the fc classs will decide when to fail the IO. With this patch if I pull a cable then IO that had reached the driver, will be failed with DID_TRANSPORT_DISRUPTED. The fc class will then fail the IO when the fast io fail tmo has fired.
