 Adapters (ENA)

Hi Netanel,

Looks like the last round of internal review went to {lkml,netdev,etc},
so this should be considered a RFC patch.

The description still needs work.

I would say "this is a driver for a device that will be available in
the future." I wouldn't say "He is expected to released soon."

Obviously this is a placeholder. I think that the included
documentation in ena.txt and in the code provides a reasonable theory
of operation, and you don't necessarily need to provide a pointer
here. If/when a full specification is available you can submit a patch
to ena.txt that points to the canonical location.
