[Xueming Li]

V4:

- Replaced with DEV_TX_OFFLOAD_IP_TNL_TSO

- Splited PKT_TX_TUNNEL_UNKNOWN into PKT_TX_TUNNEL_IP and PKT_TX_TUNNEL_UDP

V3:
- Add VXLAN-GPE and GRE extention support to testpmd csum forwarding enginee
- Split DEV_TX_OFFLOAD_GENERIC_TNL_CKSUM_TSO into DEV_TX_OFFLOAD_GENERIC_TNL_CKSUM

This patchset introduces new HW capability of generic tunnel cheksum and TSO offloads, HW supporting generic tunnel checksum and TSO could handle new tunnel type offloading w/o upgrading HW. 
New Generic tunnel checksum and TSO offload support IP tunnel and UDP tunnel. Please note that tunnel type that has length, sequence id or checksum are not considered as generic tunnel type.

Xueming Li (4):
  ethdev: introduce Tx generic tunnel L3/L4 offload
  app/testpmd: testpmd support Tx generic tunnel offloads
  app/testpmd: add more GRE extension to csum engine
  app/testpmd: introduce VXLAN GPE to csum forwarding engine
