Hi Kyle,
It may be a good solution using OVS and lldpad. But here additional software
components need to be integrated to OVS, it may make things a bit complicated.
If we just modify a little codes or add some Openflow rules to implement VEPA in OVS,
it's easy to use VEPA by installing only OVS as before.
