MTPTPT register is used to set which message types should arrive under which PTP trap. Currently, PTP0 is used for event message types, which means that the packets require time stamp. PTP1 is used for other packets. This configuration will be same for Spectrum-2 and newer ASICs. In preparation for Spectrum-2 PTP support, add helper functions to configure PTP traps and use them for Spectrum-1. These functions will be used later also for Spectrum-2.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
