31.4.2. Length Field
The length field is used to specify the number of bytes to transfer per descriptor. The length field is also used for streaming to memory-mapped packet transfers. This limits the number of bytes that can be transferred before the end-of-packet (EOP) arrives. As a result, you must always program the length field. If you do not wish to limit packet based transfers in the case of Avalon® -ST to Avalon® -MM transfers, program the length field with the largest possible value of 0xFFFFFFFF. This method allows you to specify a maximum packet size for each descriptor that has packet support enabled.
