[U-Boot-Users] Network problem in u-boot.

[André Berggren]

Hi Stefan,

CONFIG_NET_MULTI wasn't enabled. When I enable it the "miiphy_register: non
unique device name 'ppc_4xx_eth0'" is exchanged with "Trying ppc_4xx_eth0", but it doesn't solve the main problem.
See output below.

OK.

  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This is a problem recently added to the 4xx ethernet driver. I haven't found 
the time to fix it yet.

See above.

I assume, that you don't have CONFIG_NET_MULTI enabled right now. Correct? As 
a simple workaround for this problem, please enable CONFIG_NET_MULTI in your 
config file. And please let me know, if this helped.

Best regards,
Stefan
