logMinDelayReqInterval is not updated with the value from the received relay_response frame
According to IEEE1588-2019 logMinDelayReqInterval shall be updated with the value incoming in the delay_response frame.
9.5.11.2 Timing requirements
NOTE 1 - The portDS.logMinDelayReqInterval value is the logMessageInterval field of the last Delay_Resp message received in response to a Delay_Req message issued by the PTP Port.
7.7.2.4 Delay_Req message transmission interval
The portDS.logMinDelayReqInterval shall specify the minimum permitted mean time interval between successive Delay_Req messages, that is, the minDelayRequestInterval, sent by a Slave PTP Instance to a specific PTP Port on the Master PTP Instance (see 9.5.11.2). This value is determined and advertised by a Master PTP Instance based on the ability of the Master PTP Instance to process the Delay_Req message traffic. The minimum and maximum values shall be integer values specified in the applicable PTP Profile.
