### SAI API

The NVGRE Tunnel feature require at least `SAI 1.9` or above.

Some aspects of the SAI API in the initial implementation are not described in the HLD. They should be described:

  • SAI_TUNNEL_ATTR_PEER_MODE_P2MP (default)
  • Only decap mapper entries are created, not encap mapper entries

More importantly, the implementation does not conform to normal SAI tunnel usage. While the implementation seems to be focused on decap, there does not seem to be any code creating sai_tunnel_term_table entries. As far as I know the SAI tunnel definitions, I do not believe any packets will be consumed without entries in the sai_tunnel_term_table. Just creation of sai_tunnel objects is not enough.
