After aligning with Jingjing, she have already sent ABI change announcement for 
struct 'rte_eth_fdir_flow'to extend input set of FD, refer to[1].
And change of struct 'rte_eth_tunnel_flow' I want to announce can be included 
in hers, so I don't need to announce it again. Thanks.

For i40e flow director, it can use more fields such as inner destination IP, 
inner MAC outer destination MAC and outer destination IP to do classification 
for tunneling packet.
Otherwise, we also can use this structure to store tunnel flow configuration, 
not just for classification.

You have not explained what the changes are for.
So it's really difficult to have an opinion.
Please describe an use case.

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.
