The struct 'rte_eth_tunnel_flow' is only used by struct 'rte_eth_fdir_flow' now, but its name is generic,
and I plan to extend new fileds like below to support generic configuration for tunneling packet.

struct rte_eth_tunnel_flow {
	enum rte_eth_fdir_tunnel_type tunnel_type; /**< Tunnel type to match. */
        uint32_t tunnel_id;                        /**< Tunnel ID to match. TNI, VNI... */
	uint16_t flags;
	struct ether_addr outer_mac_src;
	struct ether_addr outer_mac_dst;
	union {
		struct rte_eth_ipv4_flow outer_ipv4;
		struct rte_eth_ipv6_flow outer_ipv6;
       };
	uint16_t dst_port;
	uint16_t src_port;
        struct ether_addr mac_addr;                /**< Mac address to match. */
	union {
		struct rte_eth_ipv4_flow ipv4;
		struct rte_eth_ipv6_flow ipv6;
	};
 };

Note: It have not finalized yet.
