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

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.

default y
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.
