SPI Pack of length in SDK 11.0

hi,

The SPI pack's maxsize is 255?

ret_code_t nrf_drv_spi_transfer(nrf_drv_spi_t const * const p_instance,
                                uint8_t const * p_tx_buffer,
                                uint8_t         tx_buffer_length,
                                uint8_t       * p_rx_buffer,
                                uint8_t         rx_buffer_length);

How to change the SPI pack length.
