El buf (dma cookie) y len almacenados en esta estructura se pasan a dma_unmap_single() por stmmac_tx_clean(). La DMA API requiere que la dma cookie pasada a dma_unmap_single() sea la misma que el valor devuelto desde dma_map_single(). Sin embargo, al mover la asignación más tarde, este no es el caso cuando priv->dma_cap.addr64 > 32 como \"des\" es desplazado por proto_hdr_len. Esto causa problemas como: dwc-eth-dwmac 2490000.ethernet eth0: el mapa DMA de transmisión falló y con DMA_API_DEBUG habilitado: DMA-API: dwc-eth-dwmac 2490000.ethernet: el controlador del dispositivo intenta +liberar memoria DMA que no ha asignado [dirección del dispositivo=0x000000ffffcf65c0] [tamaño=66 bytes] Solucione esto manteniendo \"des\" como la cookie DMA original y use tso_des para pasar la cookie DMA de desplazamiento a stmmac_tso_allocator().
