Mac address in the DTS file

[smitha.vanga at wipro.com]

Hi Scott,

In my DTS file for mpc8247 I have defined the ether MAC in the node as below.

ethernet at 24000 {
                       #address-cells = <1>;
                       #size-cells = <0>;
                       device_type = "network";
                       device-id = <1>;
                       compatible = "fs_enet";
                       model = "FCC";
                       reg = <11300 20 8400 100 11380 30>;
                       mac-address = [ 00 e0 ee 00 05 2e ];
                       interrupts = <20 2>;
                       interrupt-parent = <10c00>;
                       phy-handle = <2452000>;
                       rx-clock = <13>;
                       tx-clock = <12>;
               };


The driver is working and everything is fine. But as I defined the mac-address as 00:e0:ee:00:05:2e
Its constant. Am not able to change this mac -address in linux once the target is up with LINUX.
How do I change the MAC address. If different targets boards are connected on the network then every board will have the same MAC address as  the .dtb file is the same. How to go about this problem?
It would be a great help if you answer soon.

Regards,
Smitha
