Namespaces for IP over IEEE 1394

Registry Name: CSR Protocol Identifiers
Reference: [RFC2734]
Registration Procedures: IANA allocation

Note:
The configuration ROM for IP-capable nodes contains at least
one unit directory that identifies a unit architecture specified
by either RFC 2734 or RFC 3146.  The 48-bit unit architecture
identifier consists of a 24-bit Unit_Spec_ID value and a 24-bit
Unit_SW_Version value; the use of these configuration ROM entries
is specified by ISO/IEC 13213:1994.

For IP (both IPv4 and IPv6) over 1394, the value of Unit_Spec_ID 
is 0x00 005E, the company ID assigned to IANA by the IEEE Registration 
Authority.

The following values have been registered for the Unit_SW_Version:

Registry:
Value         Description                     Reference
---------       --------------                  ---------
0x00 0000       Reserved                        [RFC2734]
0x00 0001       IPv4 over IEEE 1394             [RFC2734]
0x00 0002       IPv6 over IEEE 1394             [RFC3146]
0xFF FFFF       Reserved                        [RFC2734]


Registry Name: MCAP (Multicast Channel Allocation Protocol) Parameters
Reference: [RFC2734]
Registration Procedures: not defined

Note:
Section 9.1 of [RFC2734] defines MCAP group address descriptors,
which include an 8-bit type name space.

-------  ---------------------------------  ---------
0        Reserved
1        IPv4 Multicast Address             [RFC2734]
2        IPv6 Multicast Address             [RFC3146]
3-254    Unassigned
