[ Upstream commit 45375814eb3f4245956c0c85092a4eee4441d167 ]
Fix a crash in the ethtool YNL implementation when Hardware Clock information
is not present in the response. This ensures graceful handling of devices or
drivers that do not provide this optional field. e.g.
Traceback (most recent call last):
File "/net/tools/net/ynl/pyynl/./ethtool.py", line 438, in <module>
main()
~~~~^^
File "/net/tools/net/ynl/pyynl/./ethtool.py", line 341, in main
print(f'PTP Hardware Clock: {tsinfo["phc-index"]}')
~~~~~~^^^^^^^^^^^^^
KeyError: 'phc-index'

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.
