  10         ---help---
  11           DMA engines offload copy operations from the CPU to dedicated
  12           hardware, allowing the copies to happen asynchronously.

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

  33           Enable support for the Intel(R) I/OAT DMA engine.
