[Bug 315947] Re: forcedeth NIC fails to operate

I am still not able to connect to my wired connection. Using DHCP, it
never receives a dhcp offer and when set to static it is not able to
send or receive any packets.

I was wondering if the link comes up during boot, and tried: 
sudo rmmod -f forcedeth
sudo modprobe forcedeth phy_power_down=0

and created a /etc/modprobe.d/forcedeth.conf but still no luck.

Ethernet works in Win --- Can somebody help .... Thanks
