The value of tmnxOamTrCtlSrcAddress specifies the IP host address to
be used as the source for performing an OAM Trace Route operation.
The host address type is determined by the value of the corresponding
tmnxOamTrCtlSrcAddrType object. This is an optional parameter.
This object is valid only when the tmnxOamTrCtlTestMode has a
value of 'icmpTraceRoute' or 'lspTraceRoute'.
