No reason I can think of of making them default y Most people don't have the hardware and with default y they just pollute lots of configs during make oldconfig.

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.
