If it gets sent to netdev, it's for a networking driver, and it says
"PATCH" rather than "RFC" or "please review" or "don't apply" you
cannot reasonably expect me to not look into applying the thing.

And if you're saying that patches for this device should start not
going through me, and the tactic to accomplish that is to move the
bulk of the driver into some driver/shared area, that's really weird.

Anyways I didn't push the patch out to kernel.org yet so it's easy for
me to remove it.
