Setup NTPL command

The Setup NTPL command is used for configuring in-line transmission (see DN-0449 and DN-1128). The UseWL parameter in the Setup command specifies whether wire length is used instead of capture length for length calculations in connection with transmission.

In the Huntington Beach 3 release the default value of the UseWL parameter was True, whereas in Huntington Beach 4.1 the default value is FALSE. This means that for applications using descriptor types containing a wire length field, for instance the standard packet descriptor or dynamic descriptor 3, UseWL must now be set to True in order for the wire length to be used in length calculations.

When using descriptor types such as dynamic descriptors 1, 2 and 4 that do not contain a wire length field, UseWL must be FALSE.
