If, and only if, the target in question is one known to set residual in 
status correctly. Unfortunately, there are a number of targets still out 
there that don't set residual status correctly. This has led to a 
situation where a number of initiator drivers then ignore residual if 
the device type is, say, DIRECT ACCESS and the command isn't one of the 
commands one would expect residuals on.
