Merge branch 'ethtool-hw-timestamping-statistics'
Rahul Rameshbabu says:
====================
ethtool HW timestamping statistics
The goal of this patch series is to introduce a common set of ethtool
statistics for hardware timestamping that a driver implementer can hook into.
The statistics counters added are based on what I believe are common
patterns/behaviors found across various hardware timestamping implementations
seen in the kernel tree today. The mlx5 family of devices is used
as the PoC for this patch series. Other vendors are more than welcome
to chime in on this series.
