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?
