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.
