Hi, Xiaoyu

There is a couple of small points to note:
1) It would be good to have the testpmd flow create command sample with new tunnels in commit log.
2) is it OK: "mlx5_flow_tunnel_ip_check(items, &last_item); " ?
    It looks like a bug, should the second parameter be "&item_flags" ? (if so - please, fix all
   calls of mlx5_flow_tunnel_ip_check()) 

WBR,
Slava

Subject: [Suspected-Phishing][PATCH v3] net/mlx5: support IP-in-IP tunnel

Enabled IP-in-IP tunnel type support on DV/DR flow engine.
This includes the following combination:
 - IPv4 over IPv4
 - IPv4 over IPv6
 - IPv6 over IPv4
 - IPv6 over IPv6

MLX5 NIC supports IP-in-IP tunnel via FLEX Parser so need to make sure fw
using FLEX Paser profile 0.

  mlxconfig -d <mst device> -y set FLEX_PARSER_PROFILE_ENABLE=0
