I have not seen anyone talk about NIGGIGA, but it is a highly recomend chipset. The switch should not matter, i have teste the port with other 10G equitment and confirmed it works, and I have tryed this equitmetn on moutiple ports and it stil doest not show in unraid. But I have seen it asked for on other posts so I included it here. The 4x motherboard ethernet ports work fine connected to the same switch.
