SYNOPSIS

              struct ibv_flow_action *
              mlx5dv_create_flow_action_packet_reformat(struct ibv_context *ctx,
                                    size_t data_sz,
                                    void *data,

                                    enum mlx5dv_flow_table_type ft_type)

DESCRIPTION

       Create a packet reformat flow steering action.  It allows adding/removing packet headers.

ARGUMENTS

       ctx

              RDMA device context to create the action on.

       data_sz

              The size of *data* buffer.

       data

              A buffer which contains headers in case the actions requires them.

       reformat_type

              The reformat type to be create. Use enum mlx5dv_flow_action_packet_reformat_type.

              MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TUNNEL_TO_L2:   Decap   a   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 or MAC + vlan (14 or 18 bytes)  to
              be appended to the packet after the decap action.

              MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L3_TUNNEL:  Will do encap where is L2
              of the original packet will not be included.   data  should  be  the  encapsulating
              header.

       ft_type

              It defines the flow table type to which the packet reformat action
              will be attached.

RETURN VALUE

       Upon   success   mlx5dv_create_flow_action_packet_reformat   will   return  a  new  struct
       ibv_flow_action object, on error NULL will be returned and errno will be set.
