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

20 ---help---
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.
