Hi Haoyu,

No.  The network action sub-stack is for all solutions.  

In your solution, you have an Extension Header Label.  That is the entirety of the network action sub-stack in your solution.  You have then placed NAI and AD in PSD.

I cannot write text that is so clear that no one can misread into it what is not present in the text.  I can only write clear, unambiguous text.
