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

| 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. |
