SYNOPSIS
#include <infiniband/mlx5dv.h>
struct ibv_flow_action *
mlx5dv_create_flow_action_packet_reformat(struct ibv_context *ctx,
size_t data_sz,
void *data,
enum mlx5dv_flow_action_packet_reformat_type reformat_type,
enum mlx5dv_flow_table_type ft_type)
DESCRIPTION
Create a packet reformat flow steering action. It allows adding/remov-

generic L2 tunneled packet up to inner L2.
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L2_TUNNEL: Generic
encap, data should contain the encapsulating headers.
MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L3_TUNNEL_TO_L2: Will do
decap where the inner packet starts from L3. data should be MAC

It defines the flow table type to which the packet reformat action
