Hit a little hitch with implementing polling packet counts. The poller works fine---aside from breaking forwarding within the fabric.

The problem is that I'm only able to push one layer of label and I need to edit the label twice. I could push metadata instead, and then push the complete label in a single action, but that would scale quadratically in the number of switches. I also thought about using the vlan pcp field as a bonus tag, but that seemed a little bit messy. Plus that's only 3 bits, so it limits me to 8 switches.

So instead I'm gonna use a development branch of ovs with MPLS support. It's doing it the proper way, but for the time being it is pretty much completely unsupported by anything else.
