EDIT SOLVED = Deleting "network.cfg and network-rules.cfg at the same time and rebooting resolved this. 
 
I installed a Mellanox ConectX-3 10Gb NIC and it works fine to my UniFi Agg switch. My MoBo already has two 1Gb eth ports. I am trying to assign the new card NIC as eth0 but it is not in the dropdown menu as an option under interface rules. I can only see the two 1Gb ports. I have read about 50 post with similar questions but none of their solutions helped me. 
 
I have tried to delete the contents of "network-rules.cfg" and reboot I have tried switching back to a 1Gb port in hopes of "freeing up" the 10Gb NIC.  I have set all three ports to different subnets in case that was an issue.  And attached diagnostics in case someone can help.  I have tried running: ifconfig -s -a and I get:
