I have onboard GeForce 7100/630i chipset which is nVidia MCP73 ethernet. I had some success using the nge driver instead of the rge driver. I tried both but nge seems to work because it was written for MCPxx which is PHY type of card.
The only problem is ifconfig -a shows the MAC reversed and missing a digit. Obviously this is not a perfect solution. But, I can use the interface. Internet works, ping, etc. all work. I am running on Solaris 10 10/08/ I hope this helps people. I will try to get the code for nge if it is available and maybe I can understand why the MAC is messed-up. I hope I will not cause problems for myself with this driver. -- This message posted from opensolaris.org
