That PCI ID - pciex10ec,8168 indicates that the card is on a PCI Express bus, with vendor ID 10ec and device ID 8168. If you search /etc/driver_aliases using this line:
cat /etc/driver_aliases | grep 10ec you should see that your PCI ID is listed alongside the "rge" driver (for Realtek Gigabit Ethernet cards). If so, please try typing the following command as root: ifconfig -a plumb then run ifconfig -a and post the output here. You should see a network interface named "rge0", along with 2 instances of "lo0" - one for IP version 4, one for IP version 6. Cheers Andrew. This message posted from opensolaris.org
