Could xfer.rx_buf for the data path point to the currently allocacted socket buff struct spi_transfer xfer = { 0 }; struct spi_message msg;
if (header_type == OA_TC6_DATA_HEADER) { xfer.tx_buf = tc6->spi_data_tx_buf; xfer.rx_buf = tc6->spi_data_rx_buf; } else { xfer.tx_buf = tc6->spi_ctrl_tx_buf; xfer.rx_buf = tc6->spi_ctrl_rx_buf; } xfer.len = length;
To avoid an additional copy here?
