Z8530_DMA_RX(9) Internal Functions Z8530_DMA_RX(9)NAME
z8530_dma_rx - Handle a DMA RX event
void z8530_dma_rx(struct z8530_channel * chan);
Channel to handle
Non bus mastering DMA interfaces for the Z8x30 devices. This is really pretty PC specific. The DMA mode means that most receive events are
handled by the DMA hardware. We get a kick here only if a frame ended.
