362 This enables the use of DMA engines in the network stack to
363 offload receive copy-to-user operations, freeing CPU cycles.
Dan Williams9c402f42008-06-27 01:21:11 -0700364
365 Say Y here if you enabled INTEL_IOATDMA or FSL_DMA, otherwise
366 say N.

372 This allows the async_tx api to take advantage of offload engines for
373 memcpy, memset, xor, and raid6 p+q operations. If your platform has
374 a dma engine that can perform raid operations and you have enabled
375 MD_RAID456 say Y.
376
377 If unsure, say N.

383 Simple DMA test client. Say N unless you're debugging a
384 DMA Device driver.
