SYNOPSIS

              #include <infiniband/mlx5dv.h>

              struct ibv_flow_action *
              mlx5dv_create_flow_action_modify_header(struct ibv_context *ctx,
                                  size_t actions_sz,
                                  uint64_t actions[],
                                  enum mlx5dv_flow_table_type ft_type)

DESCRIPTION

       Create a modify header flow steering action, it allows mutating a packet header.

ARGUMENTS

              The size of actions buffer in bytes.

       actions
              A buffer which contains modify actions provided in device spec format (i.e. be64).

       ft_type
              Defines the flow table type to which the modify header action will be attached.

              MLX5DV_FLOW_TABLE_TYPE_NIC_RX: RX FLOW TABLE

              MLX5DV_FLOW_TABLE_TYPE_NIC_TX: TX FLOW TABLE

RETURN VALUE

       Upon  success mlx5dv_create_flow_action_modify_header will return a new struct ibv_flow_action object, on
       error NULL will be returned and errno will be set.
