[ndnSIM] Set tag to wifi attributes

[Junxiao Shi]

Hi Zhongxiang

As I understand, your question is: in an application, you want to tag a
packet with a value that is related to an attribute of a WifiNetDevice.
In ns-3, this can be achieved with:

   1. Get hold of Ptr<Node>, by looking up NodeList with current execution
   context ID.
   2. Enumerate NetDevices attached to the Node.
   3. Find the WiFiNetDevice, and read its attribute.
   4. Tag the packet.


Yours, Junxiao
