for the specific SCSI target.
@param[in] Timeout The timeout in 100 ns units to use for the execution
of this SCSI Request Packet. A Timeout value of
zero means that this function will wait indefinitely
for the SCSI Request Packet to execute. If Timeout
is greater than zero, then this function will return
EFI_TIMEOUT if the time required to execute the SCSI
Request Packet is greater than Timeout.

for details on the possible return values.
@param[out] TargetStatus The status returned by the SCSI target specified
by ScsiIo when the SCSI Request Packat was executed
on the SCSI Host Controller. See the EFI SCSI I/O
