escription of problem:
Add a new VLAN,change the VLAN tag from 0 to 1 manually,select the eth0 as parent interface,and then click finish,it will fail.

Version-Release number of selected component (if applicable):

3. Click + button
4.Select interface type as 'VLAN', click Forward button.
5 Select start mode as 'none', enable "Activate now", fill VLAN tag as 1(The default value is 0) manually,do not use the arrows.

6.And then,choose eth0 as parent interface. Click Finish button.


Actual results:

synchronize with VLAN tag 1, still is eth0.0.
2.After click "Finish" ;
"Error creating interface: 'Could not create interface: Interface not 
found: couldn't find interface named 'eth0.0'' pop up.
3.Close the Error diaglog,and then click "cancel".
The eth0.1 was created, but with Inactive status.

will change to 'eth0.1',then click Finish,it will create successfully.

Thanks for the report, fixed upstream. But not really worth the effort of a backport for this small issue, closing as UPSTREAM.
