    This is a broadast address. Are you sure it isn't the destination MAC in the dhcp request address?

    Which evaluation kit do you have?

    This is a Nios Embedded Evaluation Kit Cyclone III edition

    and I was looking at the dhcp server log, so this is really the source MAC

    once it was 07:ff:ff:ff:ff:ff, see the log line below

    daemon.log.0:Mar 17 16:43:04 obsfrog dhcpd: DHCPDISCOVER from 07:ff:ff:ff:ff:ff via eth0: unknown client

    then it was ff:ff:ff:ff:ff:ff ?????

    daemon.log.0:Mar 17 16:46:57 obsfrog dhcpd: DHCPDISCOVER from ff:ff:ff:ff:ff:ff via eth0: unknown client

    we expected it to be something like

    00:07:ed..... (altera device) on board near RJ45

    You can try and erase the last page of the flash, and then the Nios application should ask you to type the board's serial number to generate a new Mac.

    This will only work if you are using an example software with network_utilities.c
