- ptp_hw: ptp_hw_adj_freq() (ETH_MAC_ESP_CMD_ADJ_PTP_TIME, absolute ppb vs nominal, clamped +-500 ppm, retried while the addend update is busy) and ptp_hw_step() (read + write time). - ptp_clock: first Sync after a GM is selected seeds the integral with the measured rate and steps the clock; then linuxptp-style PI (kp/ki from the Sync interval: 0.7/0.3 at 1 s). Re-step above 1 ms. Locked after 8 Syncs with |offset| < 1 us, unlocked after 3 above; GM change or loss unlocks and keeps the frequency (holdover). - Verified vs ptp4l: stepped to GM time, locked after ~19 s; locked offset within +-510 ns (mostly < 300 ns), correction +39.9 ppm (crystal -39.8 ppm), path delay ~10.2 us.

aes67-ESP32-P4
AES67 sender for the Waveshare ESP32-P4-ETH (PoE): Spotify Connect and HLS/m3u8 streams out as an AES67 multicast stream, PTP-locked, with a simple web UI for settings and SDP export.
