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 address=0x000000ffffcf65c0] [size=66 bytes]\n\nFix this by maintaining \"des\" as the original DMA cookie, and use\ntso_des to pass the offset DMA cookie to stmmac_tso_allocator().\n\nFull details of
