OK. But isn't br0.15 supposed to work like this: all vlan tagged traffic with 
tag different from 15 is discarded, all non-tagged traffic is given to br0. 
This is how it works with a vlan on top of physical devices like eth0 if I 
read the code correctly, but it doesn't currently work like that for vlan on 
top of a logical bridge device. The vlan code only sees tagged packets if the 
packets are destined for the bridge box itself, so bridged traffic is 
unaffected.
This is why I think a vlan device on top of br0 in Linux is currently useless.
