To my understanding, any unicast transport method other than block write
to the unicast FIFO are outside the scope of RFC 2734.  At the end of
section 7:
"""
   Unicast IP datagrams whose quality of service is best-effort SHALL be
   contained within the data payload of 1394 block write transactions [...]
"""
"""
   Unicast IP datagrams that require quality of service other than
   best-effort are beyond the scope of this standard.
