This field specifies the length, in bytes, of the Identifier to be transferred
from the application client to the device server. The maximum value for
this field is 64 bytes. A parameter list length of 0 indicates that no data
will be transferred, and that subsequent REPORT DEVICE IDENTIFIER
commands will return an Identifier length of 0. If the parameter list length
exceeds 64 bytes, then the drive returns a Check Condition status with
the sense key set to Illegal Request, and an additional sense code of In-
valid Field in CDB.
 
The value reported in this field is the data to be returned by all
subsequent REPORT DEVICE IDENTIFIER commands, until a new
SET DEVICE IDENTIFIER command is issued that changes the
data.
