[microblaze-uclinux] opb_ethernet HWaddr of 00:00:00:00:00:00

[<victor-sv_yeo@xxxxxxxxxxx>]

Hi,	

I use the opb_ethernet logic core and with linux 2.6 kernel. There is a problem with this Ethernet core in linux.

# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:00
          BROADCAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
                    Interrupt:1

I set the Ethernet MAC address to 00:00:5e:00:fa:ce in "make menuconfig", but My HWaddr in ifconfig is all zeros.

When I issue this command:

# ifconfig eth0 hw ether 00:11:22:33:44:55
SIOCSIFHWADDR: Device or resource busy

I cannot change the MAC address in linux. Is that a problem with opb_ethernet driver (Xilinx 10/100 OPB ETHERNET support)?

Thank you,
Victor Yeo
