net/mlx5: support generic tunnel offloading
This commit adds support for generic tunnel TSO and checksum offload. PMD will compute the inner/outer headers offset according to the mbuf fields. Hardware will do calculation based on offsets and types. Signed-off-by: Xueming Li <xuemingl@mellanox.com> Acked-by: Yongseok Koh <yskoh@mellanox.com>
