       tx_cfg
           Current TX path configuration

       rx_cfg
           Current RX path configuration

       num
           Port number

       shared
           Set when port can be shared by different clients

       claimed
           Reference count of clients which claimed the port

       lock
           Serialize port claim

       async
           Asynchronous transfer callback

       setup
           Callback to set the HSI client configuration

       flush
           Callback to clean the HW state and destroy all pending transfers

       start_tx
           Callback to inform that a client wants to TX data

       stop_tx
           Callback to inform that a client no longer wishes to TX data

       release
