Mac address in the DTS file

From: <hidden>

Hi Scott,

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

ethernet@24000 {
                       #address-cells =3D <1>;
                       #size-cells =3D <0>;
                       device_type =3D "network";
                       device-id =3D <1>;
                       compatible =3D "fs_enet";
                       model =3D "FCC";
                       reg =3D <11300 20 8400 100 11380 30>;
                       mac-address =3D [ 00 e0 ee 00 05 2e ];
                       interrupts =3D <20 2>;
                       interrupt-parent =3D <10c00>;
                       phy-handle =3D <2452000>;
                       rx-clock =3D <13>;
                       tx-clock =3D <12>;
               };


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

Regards,
Smitha
