In kernel API of Linux FireWire subsystem, handlers of isochronous receive (IR) context can get context headers as an argument of callback. When 4 byte header is used, the context header includes isochronous packet header for each packet. When 8 byte header is used, it includes isochronous cycle as well. ALSA IEC 61883-1/6 engine uses 4 byte header, and computes isochronous cycle from the cycle of interrupt. The usage of 8 byte header can obsolete the computation. Furthermore, this change works well for a case that a series of packet in one interrupt includes skipped isochronous cycle, This commit uses 8 byte header to handle isochronous cycle.
