This RFC patch adds functions to get and set DMA Coalescing feature
configuration.

Signed-off-by: Carolyn Wyborny <redacted>

What in the world is "DMA Coalescing feature", what does it do?

Might it want parameters and not just want to be turned on or off?

This change, at a minimum, needs a more descriptive commit log entry.
So that other driver authors can understand what exactly the feature
is and therefore whether they might like to add support for it to
their drivers.
