Re: PPC4xx enet driver problem (version 2.0)

["DaveyWu" <daveywu@transengines.com>]

Stefan,

Thanks for your reply. My bootloader is OpenBios. I think the problem is not caused by the wrong MAC addresses, because when I boot the 2.4.18 kernel the MAC address of eth1 is same 00:00:00:00:00:00 but both EMACs work well.

Our engineers is continuing to work with the problem. I would like to share any achievements about the problem with you.

Best regards,
Davey Wu
