An entry in this table is created when the result of
a traceroute probe is determined. The initial 2 instance
identifier index values identify the traceRouteCtlEntry
that a probe result (traceRouteProbeHistoryEntry) belongs
to. An entry is removed from this table when
its corresponding traceRouteCtlEntry is deleted.
An implementation MUST start assigning
traceRouteProbeHistoryIndex values at 1 and wrap after
exceeding the maximum possible value as defined by the
limit of this object ('ffffffff'h).
