Open Stack

Hi,

This was a bit of a mistake on my part, I recently put together some
hardware in my home lab to try and rebuild a lab that is similar to the
lab I had, where I developed the support for provider networking, which
was documented in the following guide:

http://docs.openstack.org/developer/devstack/guides/neutron.html#neutron-networking-with-open-vswitch-and-provider-networks

With the new hardware I have, I tried to configure a DevStack install,
and followed my original guide. However, the patch that introduced
$OVS_DATAPATH_TYPE currently causes the Neutron agent to fail to start,
since unless we define $OVS_DATAPATH_TYPE, $OVS_PHYSICAL_BRIDGE is never
created.

I should have caught this during my original review of the code, but I
wasn't careful enough.

I am proposing a revert, due to the lack of documentation about
$OVS_DATAPATH_TYPE.
