Changes since V2:

 - Rebased on v3.15-rc3

 - "enable pad optimization" dropped. Testing showed Linux NFS/RDMA
   server does not support pad optimization yet.

 - "ALLPHYSICAL CONFIG" dropped. There is a lack of consensus on
   this one. Christoph would like ALLPHYSICAL removed, but the HPC
   community prefers keeping a performance-at-all-costs option. And,
   with most other registration modes now removed, ALLPHYSICAL is
   the mode of last resort if an adapter does not support FRMR or
   MTHCAFMR, since ALLPHYSICAL is universally supported. We will
   very likely revisit this later. I'm erring on the side of less
   churn and dropping this until the community agrees on how to
   move forward.

 - Added a patch to ensure there is always a valid ->qp if RPCs
   might awaken while the transport is disconnected.

 - Added a patch to clean up an MTU settings hack for a very old
   adapter model.

Test and review the "nfs-rdma-client" branch:

Thanks!
