I don't think we really need this because for this device, early 
interrupt is a bad operation
which should be avoided. I can't think of why this device need to send 
early interrupt, what
we can do is to clarify that this means loss of the remaining requests. 
A device should never
do this, if it does then loss is the expected result.
