356 This enables the use of DMA engines in the network stack to
357 offload receive copy-to-user operations, freeing CPU cycles.
Dan Williams9c402f42008-06-27 01:21:11 -0700358
359 Say Y here if you enabled INTEL_IOATDMA or FSL_DMA, otherwise
360 say N.

366 This allows the async_tx api to take advantage of offload engines for
367 memcpy, memset, xor, and raid6 p+q operations. If your platform has
368 a dma engine that can perform raid operations and you have enabled
369 MD_RAID456 say Y.

371 If unsure, say N.

377 Simple DMA test client. Say N unless you're debugging a
378 DMA Device driver.
