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/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.
