The "or 16 bits" was added to SAM after it was pointed out that a new standard was recently approved that mandated 16 bit luns. That is SBP-3 (i.e. IEEE 1394 transport). All other "current" transports shown in sam4r03.pdf, Annex A are 64 bits (with a note on "SPI-5"). Aside: Annex A shows SPI-5 (Ultra 640) as the "current" SPI standard. This is an example of where standards (or drafts) diverge from reality :-) Doug Gilbert - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
