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.

81			Hexadecimal string representation of an u24.
82
83		model_name
84			Contents of a respective textual descriptor leaf.
85

108Description:
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119		(removed in 2.6.37 after being superseded by firewire-sbp2) used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.
