-         Intel(R) offload engines enable offloading memory copies in the
-         network stack and RAID operations in the MD driver.
+         DMA engines can do asynchronous data transfers without
+         involving the host CPU.  Currently, this framework can be
+         used to offload memory copies in the network stack and
+         RAID operations in the MD driver.
