[ 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'
