+config DMA_ENGINE
+       bool "Support for DMA engines"
+       ---help---
+         DMA engines offload copy operations from the CPU to dedicated
+         hardware, allowing the copies to happen asynchronously.

+       default y
+       ---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.

+         Enable support for the Intel(R) I/OAT DMA engine.
