[c-nsp] ME3600X architecture

[Xu Hu]

Hi, Waris,
I am very interested about the 10g port license, I don't quite understand why the port need license, last time I used that port trouble shooting so much time, at last find that it need license.
Since I never see any other platform need license for the port use.

Thanks and regards,
Xu Hu
