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

---help---
|
|
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.
