Networking

alex@duo > sudo lspci|grep -i eth
00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-V
02:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03)

Hence:

• I219-V is just a PHY with TDP of just 0.5W, datasheet
• I211, datasheet is a PCIe NIC.

    link/ether 70:85:c2:66:f8:7d brd ff:ff:ff:ff:ff:ff
    altname enp0s31f6

From the above you can see that:

• eno1, a.k.a enp0s31f6, is an I219-V NIC
• enp2s0 is an I211 NIC
