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