In 1394 OHCI, the trailer quadlet of descriptor in Asynchronous Receive (AR) request context has timeStamp field, in which the 1394 OHCI controller record the isochronous cycle when the packet arrived. Current implementation of 1394 OHCI controller driver stores the value of field to internal structure as time stamp, while the implementation of FireWire character device doesn't have a field for the time stamp, thus it is not available in user space. The time stamp is convenient to some kind of application in which data from several sources are compared in isochronous cycle unit. This commit implement the new event, fw_cdev_event_request3, with an additional field, tstamp.
