One thing to be aware of. The DE2-115 uses two different Ethernet PHY chips depending on when it was made. It shouldn't matter, except that sometimes it does. The DE2-115 can also use different means of communicating between the FPGA and PHY chip. Make sure the software matches the hardware configuration of the board. You should be able to transmit without changing anything in the PHY (assuming the hardware and software configurations match). In order to receive packets, your software needs to program the MAC address into the PHY chip. Make sure that is working as well.
