On Spectrum-1, timestamps for PTP packets are delivered through queues of ingress and egress timestamps. There are two event traps corresponding to activity on each of those queues. This mechanism is absent on Spectrum-2, and therefore the traps should only be registered on Spectrum-1. Extract out of mlxsw_sp_traps_init() a generic helper, mlxsw_sp_traps_register(), and likewise with _unregister(). The new helpers will later be called with Spectrum-1-specific traps.

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.
