* ABI changes are planned for struct rte_eth_conf in order to support 
  tunneling packet configuration in unified tunneling APIs, which is the rte_eth_dev_tunnel_configure
  (uint8_t port_id, uint16_t rx_q, uint16_t tx_q, rte_eth_tunnel_conf * tunnel_conf) API is planned to add. 
  and the 'tunnel_conf' shloud be stored in global 'rte_eth_conf'.
  The release 2.2 does not contain these ABI change, but release 2.3 will, and no backwards compatibility is planned.

Is it enough clear?
