tnOamTrCtlDataSize

The value of tnOamTrCtlDataSize specifies the size of the data
portion of the Trace Route request, in octets.  The size of the message
does not include the SDP encapsulation, VC-Label (if applied) or any
DLC headers or trailers.  This parameter is optional.
              
When the OAM message is encapsulated in an IP/GRE SDP, the
IP 'DF' (Don't Fragment) bit is set.  If any segment of the path
between the sender and receiver cannot handle the message size,
the message is discarded.  MPLS LSPs are not expected to fragment
the message either, as the message contained in the LSP is not an
IP packet.
              
When the data size is specified as 1, it is interpreted as the minumum
valid data size for the trace type.
              
The minimum data size (in octets) varies with tnOamTrCtlTestMode, as
follows:
  'lspTraceRoute' with multipath DSMap   140
  'lspTraceRoute' otherwise              104
  'macTraceRoute'                          1
  'p2mpLspTrace'                         132
  'vccvTraceRoute', FEC 128 pseudowire    88
  'vccvTraceRoute', FEC 129 pseudowire   120
  'vprnTraceRoute'                         1
              
This parameter is not used by 'ethCfmLinkTrace', 'icmpTraceRoute',
'ldpTreeTrace', or 'mcastTraceRoute'.
