- Remove dev_warn()
- Implement ethtool get_ts_stats
- Support PTP_CLK_REQ_PEROUT instead of PTP_CLK_REQ_PPS
- Change to start polling Tx timestamp once descriptor done bit is set

Changes in v2:
- Link to v1: https://lore.kernel.org/all/20250102103026.1982137-1-jiawenwu@trustnetic.com/
- Fix build warning
- Convert to .ndo_hwtstamp_get and .ndo_hwtstamp_set
