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

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