Description of the bug
Template of speed and lane change using GCU:

},
To address the SI settings, we have introduced media_settings.json file. During the speed-lane change process, following ERR level log is seen:
2025 Dec 3 22:47:48.470239 ixre-egl-board74 ERR pmon#: Get value by key from STATE_DB: Unable to find key NPU_SI_SETTINGS_SYNC_STATUS state_port_table_fvs_dict {'host_tx_ready': 'true', 'state': 'ok', 'netdev_oper_status': 'down', 'admin_status': 'up', 'mtu': '9100', 'supported_speeds': '40000,100000,200000', 'supported_fecs': 'none,rs'} for lport Ethernet200
The above log is seen for every port undergoing speed-lane change.
However, the log is followed by another log:
2025 Dec 3 22:47:48.472681 ixre-egl-board74 WARNING pmon#: $$$ Ethernet200 handle_port_update_event() : op=SET DB:STATE_DB Table:PORT_TABLE fvp {'host_tx_ready': 'true', 'state': 'ok', 'netdev_oper_status': 'down', 'admin_status': 'up', 'mtu': '9100', 'supported_speeds': '40000,100000,200000', 'supported_fecs': 'none,rs', 'NPU_SI_SETTINGS_SYNC_STATUS': 'NPU_SI_SETTINGS_NOTIFIED'}

Issue is marked as HIGH as the ERR log is transient and not seen again.
Steps to Reproduce
- Use the template given above to change lane and speed.
- Look out for ERR level logs using key-word - NPU_SI_SETTINGS_SYNC_STATUS
Actual Behavior and Expected Behavior
Expectation is that ERR level logs should not appear. However, this ERR log is seen per port undergoing lane-speed change.
