/**
* fwtty_port: structure used to track/represent underlying tty_port
* @port: underlying tty_port
* The work can race with the writer but concurrent sending is
* prevented with the IN_TX flag. Scheduled under lock to
* limit scheduling when fifo has just been drained.
- * @push: work responsible for pushing buffered rx to the ldisc.
- * rx can become buffered if the tty buffer is filled before the
- * ldisc throttles the sender.
- * @buf_list: list of buffered rx yet to be sent to ldisc
- * @buffered: byte count of buffered rx
* @tx_fifo: fifo used to store & block-up writes for dma to remote
* @max_payload: max bytes transmissable per dma (based on peer's max_payload)
* @status_mask: UART_LSR_* bitmask significant to rx (based on termios)
