Spi_transfer_req L4virtio::Svr::Virtio_spi< Spi_request_handler, Epiface >::Request_processor::get_request ( )

inline

Linux prepares the SPI request in three or four data parts: 1st: transfer_head 2nd: TX buffer (not present for RX half-duplex transfers) 3rd: RX buffer (not present for TX half-duplex transfers) 4th: transfer result.

This parses the three/four Data_buffers and recreates the virtio_spi_transfer_req structure.
