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

Hi Daixiwen,

I increased the frame length from 62 to 1480 and Speed I am getting is 760 Mbps, quite good! (Which shows in the networking of Task Manager of my PC). But this frame is raw and yet to add IP Header and UDP Header to the frame by modifying the C program code.

I am wondering how I can modify this C program (available in previous attachment) to achieve this.

I am also wondering if this speed (760 Mbps) drops too much after adding IP Header and UDP Header. I think may be little but not too much. Isn't it?

one more thing, if I integrate this ethernet port with FPGA (Lets say giving input to ethernet port from FPGA after doing some processing on A/D converter output), will it still be compatible? I mean it doesn't affect in the current speed?
