The payload for the packet either comes out of a PRBS (generic packet
property) or is handed to the software as a pointer to a data array. Only
one behavior is needed to specify the payload size. This is controlled by
a generic packet property.
The software calculates the invariant CRC and the variant CRC
automatically. Generic packet properties are available to let you create
incorrect CRCs.
