I have a few of these now and I am running Linux Mint 19. I understand they boards support teaming. The motherboard does show two different MAC addresses for the onboard NICs. The 1st board I used I didn't have a problem. Running the ifconfig -a command I see all LAN interface and all of the MAC addresses are unique. The behavior of the rest of my boards all exhibit different behavior. They all seem to be defaulting to teaming/bonding and the interfaces are set to clone a specific MAC. I cannot get rid of that. I would like to use both LAN interfaces individually. When you attempt to turn on the second LAN interface it turns the 1st one off and the configuration moves over to the other LAN. Is there a way to disable this feature? All motherboards are running P4.10 firmware.
