SPP was started as a trial PoC app and name convention was not 
considered well. I think it must be revised.

nfv and vm are simply forwarding and almost same but different for 
running on host or guest. In addition, vm behaves as secondary but 
implemented as primary in guest actually.

On the other hand, vf is including worker thread for classifying or 
merging packets for more realistic usecases.

I think vf might be merged to nfv. I agree with you to reduce 
maintaining costs, so I'd like to try to consider it.

I have already refactored spp.py first because all of classes and 
methods are included in one file which makes maintaining so hard, and 
usability is poor. After done refactoring spp.py, I will start 
refactoring for secondary including name convention.
