[Intel-wired-lan] [net-next 0/6] ice: detect and report PTP timestamp issues

[Jacob Keller <jacob.e.keller@intel.com>]

This series fixes a few small issues with the cached PTP Hardware Clock
timestamp used for timestamp extension. It also introduces extra checks to
help detect issues with this logic, such as if the cached timestamp is not
updated within the 2 second window.

This introduces a few statistics similar to the ones already available in
other Intel drivers, including tx_hwtstamp_skipped and tx_hwtstamp_timeouts.

It is intended to aid in debugging issues we're seeing with some setups
which might be related to incorrect cached timestamp values.

Jacob Keller (6):
  ice: set tx_tstamps when creating new Tx rings via ethtool
  ice: initialize cached_phctime when creating Rx rings
  ice: track Tx timestamp stats similar to other Intel drivers
  ice: track and warn when PHC update is late
  ice: re-arrange some static functions in ice_ptp.c
  ice: introduce ice_ptp_reset_cached_phctime function
