I said accept them in the scan attribute, that does _NOT_ mean adding knowledge to the scsi layer. In fact if you through the linux-scsi archives about the problems those attributes had with the FC transport class I suggested moving the parsing of these attributes into the transport class, which would be the preferred method to implement this. - : 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
