I'm having trouble with the SSD201 network interface. I have multiple SSD201 boards but when I update the kernel all of them get the same mac address. When I manually change it via ifconfig it only changes temporarily and the settings are erased on reboot. So I cannot allocate IP addresses to all devices via DHCP since they all have the same MAC. Anyone does have an idea about how to deal with this problem?
