Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull more rdma updates from Doug Ledford:
 "Round two of 4.6 merge window patches.

  This is a monster pull request.  I held off on the hfi1 driver updates
  (the hfi1 driver is intimately tied to the qib driver and the new
  rdmavt software library that was created to help both of them) in my
  first pull request.  The hfi1/qib/rdmavt update is probably 90% of
  this pull request.  The hfi1 driver is being left in staging so that
  it can be fixed up in regards to the API that Al and yourself didn't
  like.  Intel has agreed to do the work, but in the meantime, this
  clears out 300+ patches in the backlog queue and brings my tree and
  their tree closer to sync.

  This also includes about 10 patches to the core and a few to mlx5 to
  create an infrastructure for configuring SRIOV ports on IB devices.
  That series includes one patch to the net core that we sent to netdev@
  and Dave Miller with each of the three revisions to the series.  We
  didn't get any response to the patch, so we took that as implicit
  approval.

  Finally, this series includes Intel's new iWARP driver for their x722
  cards.  It's not nearly the beast as the hfi1 driver.  It also has a
  linux-next merge issue, but that has been resolved and it now passes
  just fine.

  Summary:

   - A few minor core fixups needed for the next patch series

   - The IB SRIOV series.  This has bounced around for several versions.
     Of note is the fact that the first patch in this series effects the
     net core.  It was directed to netdev and DaveM for each iteration
     of the series (three versions total).  Dave did not object, but did
     not respond either.  I've taken this as permission to move forward
     with the series.

   - The new Intel X722 iWARP driver

   - A huge set of updates to the Intel hfi1 driver.  Of particular
     interest here is that we have left the driver in staging since it
     still has an API that people object to.  Intel is working on a fix,
     but getting these patches in now helps keep me sane as the upstream
     and Intel's trees were over 300 patches apart"
