[Cake] de-natting & host fairness

[Noah Causin]

Thank you for all your help.

The de-nat with dual-flow isolation works great.  I tested it 
simultaneously with two separate virtual machines, one running a Flent 
50 flows download test and the other running a Flent 8 flows download 
test.  Throughput was even between the machines, and the latency was great.
