This was already indirectly included via firedtv.h, but don't rely on it. The 4 bytes which were referred to as FIREWIRE_HEADER_SIZE are actually the source packet header from IEC 61883-4 (MPEG2-TS data transmission over 1394), not e.g. the IEEE 1394 isochronous packet header. So choose a more precise name. Also, express the payload size as a preprocessor constant too.
