When running a kernel configured with CONFIG_DMA_API_DEBUG=y a warning is issued: DMA-API: device driver tries to sync DMA memory it has not allocated This warning is the result of mapping the full range of the Rx buffer pages allocated and then performing a dma_sync_single_for_cpu against a calculated DMA address. The proper thing to do is to use the dma_sync_single_range_for_cpu with a base DMA address and an offset.
