The 'get_ts_info' callback is used for obtaining information about time stamping and PTP hardware clock capabilities of a network device. The existing function of Spectrum-1 is used to advertise the PHC capabilities and the supported RX and TX filters. Implement a similar function for Spectrum-2, expose that the supported 'rx_filters' are all PTP event packets, as for these packets the driver fills the time stamp from the CQE in the SKB. In the future, mlxsw driver will be extended to support one-step PTP in Spectrum-2 and newer ASICs. Then additional 'tx_types' will be supported.

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.
