A circular list of resources on the path where each entry
in the list consists of a resource type identifier (MAC
or PORT), an index, and its CurrentPath. If the path is
available to a resource in the node (as indicated by
'wfFddiPortAvailablePaths' or 'wfFddiMacAvailablePaths')
then that resource shall be included in the list. If the
path is not available to a resource or the underlying
hardware is not present, then that resource shall not be
included in the list. Resources currently inserted in the
Path shall appear in the list once in token order. Resources
not currently inserted in the Path shall appear once in any
position supported by the implementation.
