The CP2200/1 appears to give access to the entire 64-byte (minimum) packet, which would include everything on the above diagram except for the "Preamble and Start Frame Delimiter".  It seems that the CP2200/1 can be programmed to accept only packets addressed to itself; in that case the FPGA can strip away and ignore the first 14 bytes (it does not need the length field, as we define our own standard for the packets below, using the first data byte to specify the type of packet).  From there the FPGA can parse the data field according to the below specifications.
