NB = number of blocks. This represents the number of blocks to
transfer. The block size is based on the message frame size provided
in the ioc_facts. A value of zero indicates the entire message frame
should be copied. This is two bit value. So by setting this to
non-zero vaule, you increase performance by reducing amount of data
needing to be dma'd. The value that is stored in ioc->ReqeustNB is
sometimes a non-zero vaule, which creates a bug in mptlan, where not
the entire message frame is getting transfer to firware, resulting in
corruption. This fix sets the default to zero, thus entire message
frame is copied.

Since ncr53c8xx_attach() calls scsi_host_put(), make ncr53c8xx_release()
call scsi_host_put() too, for symmetry. Both callers already expect
it to put the host for them, so that works out nicely. While the zalon
driver does 'use' the host pointer afterwards, it only compares it for

One of the intents of the block prep function was to allow ULDs to use
it for preprocessing. The original SCSI model was to have a single prep
function and add a pointer indirect filter to build the necessary
commands. This patch reverses that, does away with the init_command
field of the scsi_driver structure and makes ULDs attach directly to the
prep function instead. The value is really that it allows us to begin
to separate the ULDs from the SCSI mid layer (as long as they don't use
any core functions---which is hard at the moment---a ULD doesn't even
need SCSI to bind).

A BUSY status returned on a write request results in a stale residual
being returned when the write ultimately successfully completes.
This can be reproduced as follows:
1) issue immediate mode rewind to scsi tape drive
2) issue write request
The tape drive returns busy. The low level driver detects underrun and
sets the residual into the scsi command. The low level driver responds
with (DID_OK << 16) | scsi_status. scsi_status is 8, hence
status_byte(result) == 4, i.e., BUSY.
scsi_softirq_done() calls scsi_decide_disposition() which returns
ADD_TO_MLQUEUE. scsi_softirq_done() then calls scsi_queue_insert()
which, on the way to resubmitting the request to the driver, calls
scsi_init_cmd_errh().
The attached patch modifies scsi_init_cmd_errh() to clear the resid
field. This prevents a "stale" residual from being returned when the
scsi command finally completes without a BUSY status.

srp transport works for target drivers without supported_mode
attribute but it would be better to use it explicitly.

This adds minimum target driver support like the srp transport does:
- fc_remote_port_{rolechg,delete} calls
scsi_tgt_it_nexus_{create,destroy} for target drivers.
- add callbacks to notify target drivers of the nexus and tmf
operation results to fc_function_template.

This adds supported_mode and active_mode attributes to
/sys/class/sys_host/hostX/ for specifying the mode that a lld supports
and the currently activated mode. The output format is similar to fc
rport roles:
luce:/sys/class/scsi_host/host0$ cat supported_mode
Initiator
luce:/sys/class/scsi_host/host0$ cat active_mode
Initiator
The mode values uses bitmap since we would support dual-mode llds in
the future like this:
luce:/sys/class/scsi_host/host0$ cat supported_mode
Initiator, Target
The supported_mode attribute looks at a scsi_host_template and the
active_mode attribute looks at a scsi_host. We would add a hook to a
scsi_host_template to change the active_mode attribute
dynamically. But now there is no hook since no lld supports that
feature.
