This series includes various mlx5 updates

1) HW definitions and support for NPPS clock settings.

2) NVMEoTCP HW capabilities and definitions 

3) crypt HW bits and definitions for upcoming ipsec and TLS improvements

4) various cleanups 

5)  Enable hash mode by default for all NICs

Liu, Changcheng Says:
=====================
When hardware lag hash mode is active, the explicit port affinity
of the QP/TIS is ignored. The steering rules inside the port-select
steering domain will determine the egress port.

To support setting explicit port affinity while using hardware lag
hash mode, a new capability of bypassing the port-select steering
domain is introduced.

The following patch series enable hash mode over NICs that support
the new capability:
5.1) Set the active port bit mask to let the firmware know which ports
   are down and which are up, so it can use this info when handling
   failover on QPs with explicit port affinity.
5.2) Remove the assignment of default port affinity by the driver as
   the user has dedicated userspace APIs to set the port affinity so
   the default configuration isn't needed anymore.
5.3) Detect and enable port-select bypass so explicit port affinity is
   honored by the firmware.
5.4) Enable hash mode by default on all NICs

When setting QP/TIS port affinity explicitly and hash mode is active
and the bypass port-select flow table capability is enabled by firmware,
firmware adds a steering rule to catch egress traffic of these QPs/TISs
and make their traffic skip the port-select steering domain. This adds
performance overhead for all QPs/TISs. The common use case is to not
set explicit port affinity(as when in hash, we don't need it). If there
is a user that does want to set port affinity, it can be done with the
dedicated userspace APIs.

Detect the bypass port-select flow table capability, set it to let
firmware know the driver supports this new capability.
