Fast Ethernet Port Subsystem
The Fast Ethernet port subsystem, shown in Figure 3-3, includes two SEEQ 10/100
EtherMACs tied to external FIFOs and controlled by a Xilinx FPGA and
PALS. Each SEEQ MAC attaches to an MMI connector through its MII interface.
The MMI connector supports a set of modules that provide fiber and UTP
connections.

Not totally sure on the HALO matching transformer, the
sticker peeled up most of the lettering, and I had to try
reading the lettering backwards. Sorry...
