  1. U-Boot has networking support for VLANs (802.1q), and CDP (Cisco
  2. Discovery Protocol).
  3. You control the sending/receiving of VLAN tagged packets with the
  4. "vlan" environmental variable. When not present no tagging is
  5. performed.
  6. CDP is used mainly to discover your device VLAN(s) when connected to
  7. a Cisco switch.
  8. Note: In order to enable CDP support a small change is needed in the
  9. networking driver. You have to enable reception of the
  10. 01:00:0c:cc:cc:cc MAC address which is a multicast address.
  11. Various defines control CDP; see the README section.
