I had a similar issue on my on board Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller for my Gigabyte GA-MA78GM-S2H v1.1 MB.
So I thought I would try it, My vendor id and device id is different then yours, i.e: # /usr/X11/bin/scanpci # pci bus 0x0002 cardnum 0x00 function 0x00: vendor 0x10ec device 0x8168 # Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller 1. I added the entry to my /etc/driver_aliases # grep 10ec /etc/driver_aliases |grep 168 rge "pci10ec,8168" You need to update yours with the /usr/X11/bin/scanpci and verify with the prtconf -Dpv and then add the line entry: nvidia "pci10de,760" to /etc/driver_aliases: 3. I added the Realtek Gigabit Ethernet controller "set ip:dohwcksum=0" work around to my /etc/system at the bottom of the file , not sure where daveu found this tidbit. # tail -1 /etc/system set ip:dohwcksum=0 3. I then ran a sys-unconfig , the system shutdown and reboots prompt you for the new and the old network to enable, along with the root password , name service questions and reboots again to initialize the Realtek Gigabit Ethernet controller. And it worked!!!! so try updating One other note the RFE's are important in the fact that are needed to be submitted to request device support for each device id , as so we all can get support for drivers in OpenSolaris also as to Regression back to Solaris 10 (see dropdown in RFE) for your Asus M3N78 Pro Realtek 8211CL Gigabit PHY Vendor 0x10de device 0x0760. -- This message posted from opensolaris.org
