11				Contents of the Configuration ROM register.
12				Binary attribute; an array of host-endian u32.
13	
14			guid
15				The node's EUI-64 in the bus information block of
16				Configuration ROM.
17				Hexadecimal string representation of an u64.

26			Read-only.  Mutable during the node device's lifetime.
27			See IEEE 1212 for semantic definitions.
28	
29			units
30				Summary of all units present in an IEEE 1394 node.
31				Contains space-separated tuples of specifier_id and
32				version of each unit present in the node.  Specifier_id
33				and version are hexadecimal string representations of
34				u24 of the respective unit directory entries.
35				Specifier_id and version within each tuple are separated
36				by a colon.

51			modalias
52				Same as MODALIAS in the uevent at device creation.
53	
54			rom_index
55				Offset of the unit directory within the parent device's
56				(node device's) Configuration ROM, in quadlets.
57				Decimal string representation.

64	Description:
65			Attributes common to IEEE 1394 node devices and unit devices.
66			Read-only.  Mutable during the node device's lifetime.
67			Immutable during the unit device's lifetime.
68			See IEEE 1212 for semantic definitions.
69	
70			These attributes are only created if the root directory of an
71			IEEE 1394 node or the unit directory of an IEEE 1394 unit
72			actually contains according entries.
73	
74			hardware_version
75				Hexadecimal string representation of an u24.
76	
77			hardware_version_name
78				Contents of a respective textual descriptor leaf.
79	
80			model
81				Hexadecimal string representation of an u24.
82	
83			model_name
84				Contents of a respective textual descriptor leaf.
85	
86			specifier_id
87				Hexadecimal string representation of an u24.
88				Mandatory in unit directories according to IEEE 1212.
89	
90			vendor
91				Hexadecimal string representation of an u24.
92				Mandatory in the root directory according to IEEE 1212.
93	
94			vendor_name
95				Contents of a respective textual descriptor leaf.
96	
97			version
98				Hexadecimal string representation of an u24.
99				Mandatory in unit directories according to IEEE 1212.

108	Description:
109			SCSI target port identifier and logical unit identifier of a
110			logical unit of an SBP-2 target.  The identifiers are specified
111			in SAM-2...SAM-4 annex A.  They are persistent and world-wide
112			unique properties the SBP-2 attached target.
113	
114			Read-only attribute, immutable during the target's lifetime.
115			Format, as exposed by firewire-sbp2 since 2.6.22, May 2007:
116			Colon-separated hexadecimal string representations of
117				u64 EUI-64 : u24 directory_ID : u16 LUN
118			without 0x prefixes, without whitespace.  The former sbp2 driver
119			(removed in 2.6.37 after being superseded by firewire-sbp2) used
120			a somewhat shorter format which was not as close to SAM.
