16.4.2.5.6. Buffer Size Calculations
If a descriptor is not marked as last (with the LD bit of the DES0 field set to 0) then the corresponding buffer(s) of the descriptor are considered full, and the amount of valid data in a buffer is accurately indicated by its buffer size field. If a descriptor is marked as last, the buffer might or might not be full, as indicated by the buffer size in the DES1 field. The driver is aware of the number of locations that are valid.† The driver is expected to ignore the remaining, invalid bytes.
