	  Intel(R) offload engines enable offloading memory copies in the
	  network stack and RAID operations in the MD driver.

config INTEL_IOATDMA
	tristate "Intel I/OAT DMA support"
	depends on PCI && X86
	select DMA_ENGINE
	select DCA
	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.

config INTEL_IOP_ADMA
	tristate "Intel IOP ADMA support"
	depends on ARCH_IOP32X || ARCH_IOP33X || ARCH_IOP13XX
	select ASYNC_CORE
	select DMA_ENGINE

	  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.
