[dpdk-dev] [PATCH v3 0/7] support generic tunnel Tx checksum and TSO

[Xueming Li]

- 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
  and DEV_TX_OFFLOAD_GENERIC_TNL_TSO
- Add PKT_TX_TUNNEL_UNKNOWN and PKT_TX_OUTER_UDP

This patchset add new HW TX capability of generic tunnel checksum and TSO
offloads, HW supporting generic tunnel offloading could handle new tunnel 
type offloading w/o upgrading HW. 

This is achieved by informing HW offsets and types of headers, HW would 
do calculation and TSO segments based on packet inner and outer headers offset
regardless of tunnel type.

Xueming Li (7):
  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
  net/mlx5: separate TSO function in Tx data path
  net/mlx5: support generic tunnel offloading
  net/mlx5: allow max 192B TSO inline header length
