[U-Boot-Users] [patch #9/11] VLAN/CDP networking support.

[Pantelis Antoniou]

Hello

The following patch adds 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.

Regards

Pantelis
