Thanks Ben,

This patch made it work for me. I have one more question. I'm trying to run
ovs on a cluster of machines that I don't have root on but I can probably
get some permissions changed on some things.

I'm wondering if you knew what would be required in order to get
ovs-oepnflowd netdev at br0 --ports=eth0 tcp:130.127.39.220:6633 working?

Running that I'm getting the following:
Apr 09 18:39:32|00001|openflowd|INFO|Open vSwitch version 1.1.0pre2

ovs-openflowd: could not create datapath (Address family not supported by
protocol)


Thanks,

Aaron
