1. Post-jump drift bootstrap: on the first Sync packet following a step jump, do not compute frequency drift against a synthesized zero delta, which previously caused the entire residual phase offset (~ms) to be mistaken for frequency drift (~million ppb) and immediately absorbed. 2. Drift rate formula: normalize the adjustment contribution by the actual measurement interval instead of the adjtime slew period, and compute natural delta rate as (delta - last_delta + last_adjtime) / interval. 3. Remove broken last_delta > delta comparison that prevented offsets from converging and applied inverted corrections on negative overshoots. 4. Correct ptp_adjtime() invocation to always pass adjustment_ns for CLOCK_REALTIME slewing rather than dropping drift compensation when delta exceeds threshold. Clamp adjustment_ns to the hardware slew limit so last_adjtime_ns accurately mirrors the true slew applied. 5. Enable Delay_Req in E2E mode once clock is tracking (not jumping) and allow software timestamping latency in ptp_process_delay_resp(). 6. Propagate initialization return code from ptpd_start() and avoid unconditional failure print in do_ptpd_start().
