Has anyone upgraded to High Sierra? My previously stable Intel X520 setup on a nMP over Thunderbolt stopped working after I upgraded. I now only get a self-assigned IP and manually configuring the IP still doesn't allow me to ping the router. Tried the various hardware settings without success. There has not been a driver update at small-tree.com since Sierra support last year. I also tried with a previously working Chelsio S310E card and got the same results, which is making me wonder if it might be a general High Sierra 10GbE issue.
