Gigabit Ethernet Interface (via Marvell 88E1111) with Cyclone IVE FPGA

e.g. you just want a point-to-point link to broadcast/receive streaming data between two boards using Ethernet as the transport.

Yes, I just want a point-to-point link to broadcast/receive streaming data from FPGA board to another device (lets say PC at the beginning) using Ethernet as the transport and Speed should be like 500 Mbps at least.

I read the link you have provided, but how can I trim down NIOS and software part from it for my purpose?
