NAME
       mlx5dv_create_flow_action_modify_header - Flow action modify header for
       mlx5 provider

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
       ctx    RDMA device context to create the action on.

       actions_sz
              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.
