examples/tep_term: add structures for VXLAN processing

Browse Source 
Add the common APIs of tunneling packet processing.

We are trying to create a framework for tunneling packet processing, which includes

  - Tunnel port configuration

  - Tunnel setup

  - Tunnel destroying

  - Tunneling packet processing for Rx side

  - Tunneling packet processing for Tx side

  - Tunnel parameter processing
