A trace route hop entry.
The first index member specifies the hpnicfFcTraceRouteEntry
that an hpnicfFcTraceRouteHopsEntry is associated with. The
second index element identifies a hop in a trace route path.
In the case of a complete path being traced, entries
corresponding to an hpnicfFcTraceRouteEntry are created
automatically in this table.
Each hop in the complete path will be listed in this table.
When an hpnicfFcTraceRouteEntry is deleted or aged out, the
entries corresponding to the hpnicfFcTraceRouteEntry in this
table are also deleted.
