Access to the ASB2305's PCnet32 NIC doesn't work correctly because when the NIC attempts to update the ring buffer flags by DMA, the change to RAM crops up about 17uS after the interrupt line is asserted. This is almost certainly due to a bug in the PCI bridge FPGA on that board. We can get around this by making dma_alloc_coherent() put the ring buffer in the SRAM attached to the PCI bridge rather than in the SDRAM.
