The DMA API requires that\nthe dma cookie passed to dma_unmap_single() is the same as the value\nreturned from dma_map_single(). However, by moving the assignment\nlater, this is not the case when priv->dma_cap.addr64 > 32 as \"des\"\nis offset by proto_hdr_len.\n\nThis causes problems such as:\n\n  dwc-eth-dwmac 2490000.ethernet eth0: Tx DMA map failed\n\nand with DMA_API_DEBUG enabled:\n\n  DMA-API: dwc-eth-dwmac 2490000.ethernet: device driver tries to +free DMA memory it has not allocated [device
