config INTEL_IOATDMA

	help
	  Enable support for the Intel(R) I/OAT DMA engine present
	  in recent Intel Xeon chipsets.

	  Say Y here if you have such a chipset.

	  If unsure, say N.

	  Enable support for the Intel(R) IOP Series RAID engines.

config NET_DMA
	bool "Network: TCP receive copy offload"
	depends on DMA_ENGINE && NET
	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.
