RDMA driver code is not to be applied to the net-next tree. We've
learned this causes too many work flow problems. 

You must co-ordinate your driver with a shared git tree as Mellanox is
doing, or wait for alternating kernel releases.

I'm not sure what to do with this PR, it is far too late in the cycle
to submit a new driver so most likely net should not go ahead with
this prep work until this new driver model scheme is properly
reviewed.

And if you expect anything to be shared with rdma you need to produce
pull requests that are based on some sensible -rc tag.
