There is a limited count of IEEE 1394 specifics:

  a) RFC 2734 ARP:  currently implemented by inspecting and mangling ARP
     packets within the firewire-net driver (inbound as well as outbound
     packets).

  b) RFC 2734 MCAP (Multicast Channel Allocation Protocol):  currently not
     implemented; not sure if needed (I see a few big downsides to using
     per-multicast-group channels); not sure if networking core support
     would be needed for this

  c) RFC 2855 DHCP for IEEE 1394:  currently not implemented; not sure if
     needed; not sure if it would concern the kernel at all

  d) RFC 3146 NDISC (Neighbor Discovery Protocol for IPv6):  That's the
     only real problem in search of a solution.

I bet there won't be any additional RFCs invented for networking over
1394, ever.
