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

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