Conntrack bridge only tracks untagged and 802.1q.
To make the bridge-fastpath experience more similar to the forward-fastpath experience, add double vlan, pppoe and pppoe-in-q tagged packets to bridge conntrack and to bridge filter chain.
Split from patch-set: bridge-fastpath and related improvements v9
