This question seems related to your board and port (Xilinx, I guess?). You *might* get more answers posting it in a forum related to your hardware, if there is any. However, you might also be lucky and someone here is using the same hardware... Not me, unfortunately.

Hi, i want to connect four EVK1100 using a switch.
In all of them i´m using lwip, and i must to configure the file conf_eth.h.
The code of this file is this:

#endif
what parameters should i change?
of course IP, and MAC? How do i define the address MAC?
shoul i change the paramter ETHERNET_CONF_PHY_ADDR and ETHERNET_CONF_PHY_ID ?
What value?
Thanks in advance!
