This strongly suggests that your FPGA board is able to deal with ARP
requests but not with the ARP responses (for the requests that it sends
out) that it's getting from the PC.  If you do the ping as above, the
FPGA board gets to know about the MAC address of the PC without having
to send out an ARP request.

I've no idea how the lwIP Xilinx port sets up and configures ARP, so
can't offer any guidance about how to fix this problem.  Perhaps someone
else who has used the Xilinx code successfully can help?
