From: Zhou Zheng Sheng <zhshzhou@linux.vnet.ibm.com> In Linux networking, a usual VLAN + bridge network setup is as the following. eth0 |-> eth0.10 -> br10 -> vnet101, vnet102, ... |-> eth0.20 -> br20 -> vnet201, vnet202, ... While the eth0 trunk and VLAN interfaces provide the isolation service, the bridges provide the switching inside the respective VLAN. It's not very useful to have a bridge device as the trunk because the VLAN interfaces on a trunk should be isolated. This patch contains changes to the back-end and front-end. The back-end checks if the front-end submits an invalid setup to use a bridge as the VLAN trunk device and raises exception. Before this patch, if the user creates a bridged network over an existing bridge with VLAN tag set. The back-end just ignores the VLAN and creates an ordinary bridged network. After this patch, the back-end raises an exception with an explanation in this case. The front-end also checks the currently selected interface type. If the selected interface is a bridge, it disables the vlan check box, otherwise it enables the vlan check box. V2 Add front-end code to disable vlan check box if the selected interface is a bridge.
