- aes67_cfg: cfg_set_number(group, key, value, apply) for firmware-side
changes, stored in NVS like a POST; apply can be skipped.
- aes67_sdp_sap: once a second, a change of the PTP GM (ts-refclk) bumps
aes67.session_ver without re-applying the aes67 group (no stream
restart); SAP then re-announces. Runs whether or not SAP is on.
- Verified with ptp4l as a normal clock (p1 128): board auto (p1 250)
steps down to SLAVE (session_ver 1->2); role master p1 100 via API ->
board MASTER at once (->3); back to auto p1 250 -> ptp4l takes over
within ~1 s, board SLAVE again (->4).
