+config DMA_ENGINE

+        ---help---
+          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.

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