A trace route hop entry.
The first index identifies the fcTraceRouteEntry
that a fcTraceRouteHopsEntry belongs to. The second
index element selects a hop in a trace route path.
Entries are created automatically in this table
corresponding to a fcTraceRouteEntry when the
trace route test completes.
In the case of a complete path being traced, the
source and destination points along with the
intermediate hops will be listed in this table.
The entries in this table corresponding to a
fcTraceRouteEntry are automatically deleted when
the fcTraceRouteEntry is deleted or aged out.
