QLA_* return codes are 'int' in size. There were still several
legacy check-points which assumed a return-code width of 8-bits.
This could cause incorrect assumptions of 'good' status if a
return of QLA_FUNCTION_TIMEOUT.

To ensure smooth operations amongst the FCoE and NIC side
components of the ISP81xx chip, the FCoE driver (qla2xxx) must
ensure the 10gb NIC driver (qlge) does not timeout waiting for
IDC (Inter-Driver Communication) acknowledgments. The
acknowledgment requirements are trivial -- a simple mirroring of
incoming mailbox registers during the AEN to a process-context
capable mailbox command.

processing path in multiq mode.
Correct response-queue-0 processing by instructing the firmware
to run with interrupt-handshaking disabled, similarly to what is
now done for all non-0 response queues. Since all
response-queues now run in the same mode, the driver no longer
needs the hot-path 'is-disabled-HCCR' test.

dev-loss-tmo/terminate_rport_io callbacks.
Commit f78badb1ae07e7f8b835ab2ea0b456ed3fc4caf4 ([SCSI] fc
transport: pre-emptively terminate i/o upon dev_loss_tmo timeout)
changed the callback semantics of dev_loss_tmo and
terminate_rport_io such that repeated calls could be made. This
could result in the the driver using stale (NULLed-out, in
dev_loss_tmo) data from the rport. Correct this by addint a
simple check to ensure a valid fcport is attached.

When clearing the flash device's SR, the comment is incorrect...
clearing the SR is 2 steps:
1. the SR protect bit is 1, so the first write zero clears only
that bit,
2. the SR protect bit is now 0, so the next write zero clears the
remaining bits.
The sector erase debug print more correctly identifies that the erase failed.

Pre-ISP81XX parts (including ISP24xx and ISP25xx) could contain a
firmware image within a segment of flash, driver would fallback
to loading this firmware if the request-firmware interface failed
(userspace .bin file). Moving forward, all ISP81XX parts will
ship with a suggested-to-be-used firmware image within flash
which all driver should first attempt to load. If the flash
firmware load fails, the driver will then fallback to loading
firmware via the request-firmware interface (ql8100_fw.bin).

3. Additional request and response queues are created at the time of vport

4. Requests are sent to the request queue that the vport was assigned

Mike Reed noted
(https://bugzilla.novell.com/show_bug.cgi?id=421330) that the
driver was incorrectly returning a SUCCESS status if the driver's
request to the firmware to abort a command failed. By doing so,
the mid-layer believed, incorrectly, that the command has
completed and has been returned (ultimately clearing
scsi_cmnd.request_buffer) yet the driver still has the command.
What should correctly happen is a mid-layer escalation
(device-reset, etc.) of recovery during which the driver will
eventually return the outstanding commands to the mid-layer.

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 better 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 (not including
tape). The fc class will then fail the IO when the fast io fail tmo
has fired, and the driver will flush any other commands running.

rport error or race
If the fcport is not online then we do not want to block IO to all ports on
the host. We just want to stop IO on port not online, so we should be using
the SCSI_MLQUEUE_TARGET_BUSY return value.
For the case where we race with the rport memset initialization
we do not want the queuecommand to be called again so we can just use
SCSI_MLQUEUE_TARGET_BUSY for this.
