Hi, I need to provide a encap/decap layer which encapsulats ethernet packets in a custom FPGA header before putting the packet on the wire and decapsulating the custom FPGA header before handing the packet off to the TCP/IP stack. I would appreciate if someone can point me to earlier work that provided a similar interface. I am working on sytem-of-chip MIPS processor in which the ethernet MAC is put in packet fifo mode to talk to the custom FPGA.
