HOLDOVER and FREERUN events are received after bringing down master interface of a BC config. 

Expect no holdover/freerun events received when master interface brought down.

ocp 4.10.59
ptp 4.10.0-202304250841

100%

1. Install SNO DU with 4.10 ptp operator and configure Boundary clock
2. ssh to the node, and bring down a master interface of the BC config. e.g., ip link eno12419 down. 
3. Check ptp events

2. HOLDOVER and FREERUN events received on slave port, followed by LOCKED events

2. No HOLDOVER or FREERUN events received on slave interface when master interface is down
