Add HW timestamping statistics support - through implementing get_ts_stats. Timestamp statistics include correctly timestamped packets, discarded, skipped and flushed during PTP release. Most of the stats are collected per vport, only requests skipped due to lack of free latch index are collected per Tx queue. Statistics can be obtained using kernel ethtool since version 6.10 with: ethtool -I -T <interface> The output will include: Statistics: tx_pkts: 15 tx_lost: 0 tx_err: 0 Signed-off-by: Milena Olech <milena.olech@intel.com> Co-developed-by: Anton Nadezhdin <anton.nadezhdin@intel.com> Signed-off-by: Anton Nadezhdin <anton.nadezhdin@intel.com> Reviewed-by: Aleksandr Loktionov <aleksandr.loktionov@intel.com> Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Samuel Salin <Samuel.salin@intel.com> Reviewed-by: Paul Menzel <pmenzel@molgen.mpg.de> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> |

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 reStructuredText 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.
