Pull rdma fixes from Jason Gunthorpe:
 "This is the next batch of for-rc patches from RDMA. It includes the
  fix for the ipoib regression I mentioned last time, and the result of
  a fairly major debugging effort to get iser working reliably on cxgb4
  hardware - it turns out the cxgb4 driver was not handling QP error
  flushing properly causing iser to fail.

   - cxgb4 fix for an iser testing failure as debugged by Steve and
     Sagi. The problem was a driver bug in the handling of shutting down
     a QP.

   - Various vmw_pvrdma fixes for bogus WARN_ON, missed resource free on
     error unwind and a use after free bug

   - Improper congestion counter values on mlx5 when link aggregation is
     enabled

   - ipoib lockdep regression introduced in this merge window

   - hfi1 regression supporting the device in a VM introduced in a
     recent patch

   - Typo that breaks future uAPI compatibility in the verbs core

   - More SELinux related oops fixing

   - Fix an oops during error unwind in mlx5"

Congestion counters are counted and queried per physical function.
When working in LAG mode, CNP packets can be sent or received on both
of the functions, thus congestion counters should be aggregated from
the two physical functions.

When mlx5_stop_eqs fails to destroy any of the eqs it returns with an error.
In such failure flow the function will return without
releasing all EQs irqs and then pci_free_irq_vectors will fail.
Fix by only warn on destroy EQ failure and continue to release other
EQs and their irqs.

In mlx5_ifc, struct size was not complete, and thus driver was sending
garbage after the last defined field. Fixed it by adding reserved field
to complete the struct size.

In addition, rename all set_rate_limit to set_pp_rate_limit to be
compliant with the Firmware <-> Driver definition.

Before the offending commit, mlx5 core did the IRQ affinity itself,
and it seems that the new generic code have some drawbacks and one
of them is the lack for user ability to modify irq affinity after
the initial affinity values got assigned.

The issue is still being discussed and a solution in the new generic code
is required, until then we need to revert this patch.

This fixes the following issue:
echo <new affinity> > /proc/irq/<x>/smp_affinity
fails with  -EIO

This reverts commit a435393acafbf0ecff4deb3e3cb554b34f0d0664.
Note: kept mlx5_get_vector_affinity in include/linux/mlx5/driver.h since
it is used in mlx5_ib driver.

Pull rdma updates from Doug Ledford:
 "This is a fairly plain pull request. Lots of driver updates across the
  stack, a huge number of static analysis cleanups including a close to
  50 patch series from Bart Van Assche, and a number of new features
  inside the stack such as general CQ moderation support.

  Nothing really stands out, but there might be a few conflicts as you
  take things in. In particular, the cleanups touched some of the same
  lines as the new timer_setup changes.

  Everything in this pull request has been through 0day and at least two
  days of linux-next (since Stephen doesn't necessarily flag new
  errors/warnings until day2). A few more items (about 30 patches) from
  Intel and Mellanox showed up on the list on Tuesday. I've excluded
  those from this pull request, and I'm sure some of them qualify as
  fixes suitable to send any time, but I still have to review them
  fully. If they contain mostly fixes and little or no new development,
  then I will probably send them through by the end of the week just to
  get them out of the way.

  There was a break in my acceptance of patches which coincides with the
  computer problems I had, and then when I got things mostly back under
  control I had a backlog of patches to process, which I did mostly last
  Friday and Monday. So there is a larger number of patches processed in
  that timeframe than I was striving for.

  Summary:
   - Add iWARP support to qedr driver
   - Lots of misc fixes across subsystem
   - Multiple update series to hns roce driver
   - Multiple update series to hfi1 driver
   - Updates to vnic driver
   - Add kref to wait struct in cxgb4 driver
   - Updates to i40iw driver
   - Mellanox shared pull request
   - timer_setup changes
   - massive cleanup series from Bart Van Assche
   - Two series of SRP/SRPT changes from Bart Van Assche
   - Core updates from Mellanox
   - i40iw updates
   - IPoIB updates
   - mlx5 updates
   - mlx4 updates
   - hns updates
   - bnxt_re fixes

The QPTS register allows changing the priority trust state between pcp and
dscp. Add support to get/set trust state from device. When the port is
in pcp/dscp trust state, packet is routed by hardware to matching priority
based on its pcp/dscp value respectively.

The QPDPM register allow channing the dscp to priority mapping. Add support
to get/set dscp to priority mapping from device.
Note that to change a dscp mapping, the "e" bit of this dscp structure
must be set in the QPDPM firmware command.
