Triple Speed Ethernet with external fifo connection issues

I also can't seem to create an interface to the receive fifo status sink or the receive packet type source. Streaming adaptors do not work; I can not use them to interface between the 5 bits per symbol of the receive packet type and, for instance, the 8 bits per symbol o a scatter-gather DMA interface. Any help or insight will be much appreciated. My design of a 4-port triple speed interface is complete but for these two types of ports.
