Public bug reported:

Open vSwitch vhost-user support via fast path detection

Fast path technology is a user-space stack for high performance packets
offloading the Linux networking functions: IPv4/IPv6 routing, linux bridge, OVS,
iptables, conntrack...

To benefit from the offloading, a VM needs to use vhost-user instead of
vhost-net backend for virtio interfaces.

As a consequence, we have a forked ML2 mechanism driver called ovs-fp.

We propose to merge this modification into the neutron tree, instead of
maintaining a fork.
