Cc: dev
Add support to below TCP segmentation offloads for
96XX A1 onwards and 95xx B0 onwards.
- TCPv4, TCPv6
- VXLAN[v4 | v6][v4 | v6]
- GENEVE[v4 | v6][v4 | v6]
This patch also modifies a fastpath function to be forced
inline due to performance reasons for multi-seg mode.

Cc: dev
Add support to below TCP segmentation offloads for
96XX A1 onwards and 95xx B0 onwards.
- TCPv4, TCPv6
- VXLAN[v4 | v6][v4 | v6]
- GENEVE[v4 | v6][v4 | v6]
This patch also modifies a fastpath function to be forced
inline due to performance reasons for multi-seg mode.

Updated missing TSO support in doc/guides/nics/features/octeontx2_vf.ini.
Only in vector mode, TSO is not supported.
Applied to dpdk-next-net-mrvl/master. Thanks

Add support to below TCP segmentation offloads for
96XX A1 onwards and 95xx B0 onwards.
- TCPv4, TCPv6
- VXLAN[v4 | v6][v4 | v6]
- GENEVE[v4 | v6][v4 | v6]
This patch also modifies a fastpath function to be forced
inline due to performance reasons for multi-seg mode.
