      1 ## VLAN
      2 ## ====
      3 ##
      4 ## Virtual LANs give you the ability to sub-divide a LAN. Linux can
      5 ## accept VLAN tagged traffic and presents each VLAN ID as a
      6 ## different network interface (eg: eth0.100 for VLAN ID 100)
      7 ##
      8 ## Some Liminix devices with multiple ethernet ports are implemented
      9 ## using a network switch connecting the physical ports to the CPU,
     10 ## and require using VLAN in order to send different traffic to
     11 ## different ports (e.g. LAN vs WAN)
