| 12 | hardware, allowing the operations 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. |
