RE: PPC4xx enet driver problem (version 2.0)

["Stefan Roese" <stefan.roese@esd-electronics.com>]

Davey!

No, we didn't solve this problem so far. Eugene did some tests on an
ppc440 board and had no problems with the multiple enet devices. So it
seems to be 405ep related! I still have to send some debug output to
Eugene (hopefully today)!

By the way: Did you notice that your MAC-address of the 2nd ethernet
channel (eth1) is 00:00:00:00:00:00? This is wrong and probably a
problem in passing MAC-addresses from your bootloader to linux. What
bootloader are you using? U-Boot/OpenBios?

Best regards,
Stefan.
