esxi 6 and Intel i211 Gigabit nic

I have a shuttle DS57U device with Intel i218-LM NIC and Intel i211 nic.  Only the i218 nic is showing up as a available adapter, the i211 isn't available as a physical nic, The hardware compatibility guide shows both of these nics as having drivers in esxi 6, so I'm trying to understand what the problem is and if there is a solution for it? Has anyone any experience with the i211 intel nic in esxi? At the end is the lspci output which shows that i211 as vmnic1, yet its not available in vsphere client under Network Adapter listing or if I try to add a new vswitch.
