  we would like to know if DMA controller is SHARED among devices or each
device has its own DMA controller. For example, if DMA controller is not
shared, does that mean each device with DMA needs a DMA controller? If there
are two network cards and one sound card in my computer, does that mean
there are THREE DMA controllers?
  Thanks a lot!
