  25           Say Y here if you have such a chipset.

  27           If unsure, say N.

  48           This enables the use of DMA engines in the network stack to
  49           offload receive copy-to-user operations, freeing CPU cycles.
  50           Since this is the main user of the DMA engine, it should be enabled;
  51           say Y here.
