Re: [PATCH net-next v4 09/12] net: ethernet: oa_tc6: implement receive path to receive rx ethernet frames

[Ramón Nordin Rodriguez]

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?
