Dear Dave,

ACL plugin is using l2 classify path for traffic diversion and also dispatching 
the dot1q/dot1ad packets to the correct ip4/ip6 acl plugin node by matching on 
the inner ethertype...

I could probably make use of this change to push some more intelligence of the 
stateless traffic matching to classifier as an acceleration measure for some 
specific cases.. (assuming the idea is to do it uniformly for input&output 
paths)..
