Description: VR interface doesn't handle vlans; this makes it work.
Note that this already works in linux>2.6.19, don't know about earlier
How-To-Repeat: Try configure a vlan, this works but then traffic fails later;
Actually crashes the system under some (unknown) circumstances.
Fix: Very simple patch enclosed
(tested; I'm sending from the running system with lots of vlans):
