IGNORE WIDE RESIDUE message has been defined in the SCSI-2 
specification and is also part of the SCSI-3 specification. As we 
have never seen such a message being sent by a target we wonder if 
anyone has ever made use of this message or will do so in the future. 

If wide transfer has been negotiated between initiator and target and 
transfer count is an odd number of bytes, then the message is not 
required as both sides know that the high byte of the last word 
transfered must be ingnored.

If wide transfer has been negotiated and transfer count is an even 
number of bytes, then why should the target disrupt the transfer at 
an odd number of bytes?
