11 | DMA engines offload bulk memory operations from the CPU to dedicated |
| 12 | hardware, allowing the operations to happen asynchronously. | |

| 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. | |
