Dell Dual Port Ethernet NIC X3959

Has anyone tried to use this in Yosemite? If you did and you were successful, do you recall what kext you used? I can't get a fix on which intel ethernet chip it is, it appears to be a Pro 1000T, but that doesn't tell me the actual chip used, it might be a 82546EB or a 82579V...

Any help out there?

Thanks!
