[ovs-dev] VXLAN ports not working with latest master

I'm running with the latest master, and I noticed I can no longer configure VXLAN ports. I'm tracking this down, but wanted to let folks on the list know as well.

I am configure my VXLAN port like this:

        ovs-vsctl add-port br2 vxlan1 -- set interface vxlan1 \
                type=vxlan options:remote_ip=192.168.1.14 options:key=flow

And I see this in the logs:

2013-02-03T20:54:11Z|00232|dpif|WARN|system at ovs-system: failed to add vxlan1 as port: Invalid argument

Upping the verbosity doesn't provide any more clues. The output of "ovs-vsctl" and "ovs-dpctl show" below seem to indicate that userspace thinks the port is there but the kernel doesn't configure it. GRE ports seem to work fine. Any ideas?

Thanks,
Kyle
