QPs which don't care from timestamp mode, should set the ts_format
to default, otherwise the QP creation could be failed if the timestamp
mode is not supported.

Pull rdma updates from Jason Gunthorpe:
 "This is quite a small cycle, if not for Lee's 70 patches cleaning the
  kdocs it would be well below typical for patch count.

  Most of the interesting work here was in the HNS and rxe drivers which
  got fairly major internal changes.

  Summary:

   - Driver updates and bug fixes: siw, hns, bnxt_re, mlx5, efa

   - Significant rework in rxe to get it ready to have XRC support added

   - Several rts bug fixes

   - Big series to get to 'make W=1' cleanness, primarily updating kdocs

   - Support for creating a RDMA MR from a DMABUF fd to allow PCI peer
     to peer transfers to GPU VRAM

   - Device disassociation now works properly with umad

   - Work to support more than 255 ports on a RDMA device

   - Further support for the new HNS HIP09 hardware

   - Coding style cleanups: comma to semicolon, unneded semicolon/blank
     lines, remove 'h' printk format, don't check for NULL before kfree,
     use true/false for bool"

pull-request: mlx5-next 2021-02-16

The patches in this pr are already submitted and reviewed through the
netdev and rdma mailing lists.

The series includes mlx5 HW bits and definitions for mlx5 real time clock
translation and handling in the mlx5 driver clock module to enable and
support such mode [1]

Internal timer mode (SW clock) requires some PTP clock related metadata
structs. Real time mode (HW clock) will not need these metadata structs.
This separation emphasize the different interfaces for HW clock and SW
clock.

Add needed structure layouts and defines for MTUTC (Management UTC)
register. MTUTC will be used for cyc2time HW translation.

In addition, add cyc2time modify capability bit and init segment HCA
real time address.

Finally, add capability bits indicating which time-stamping format is
supported per SQ and RQ. Add ts_format in the queue's context layout to
allow configuration.

* branch 'mlx5_timestamp':
  RDMA/mlx5: Fail QP creation if the device can not support the CQE TS
  net/mlx5: Add new timestamp mode bits

The traditional DevX CQ creation flow goes through mlx5_core_create_cq()
which checks that the given EQN corresponds to an existing EQ and attaches
a devx handler to the EQN for the CQ.

In some cases the EQ will not be a kernel EQ, but will be controlled by
modify CQ, don't block creating these just because the EQN can't be found
in the kernel.

These fields declare which timestamp mode is supported by the device
per RQ/SQ/QP.

In addition add the ts_format field to the select the mode for
RQ/SQ/QP.
