I actually see a comment about this patch at https://github.com/richardcochran/linuxptp/commit/2a2532d66121d0060b042c5bd6020a62153f1e0a
stating that "it seems that this commit breaks compatibility with some GMs, e.g., Microchip's TP4100. Tested with G.8275.2 profile. The reason being that this particular GMs do not reply to Delay_Req messages with minor version set to 1. Below find a fragment of the Delay_Req message from wireshark dump, which is not being replied to. As soon as I change the minorVersionPTP to 0, the appropriate Delay_Resp is being sent. All other messages work just fine (Signaling requests, etc.)." ... could be that the issue is with my use of a White Rabbit Switch acting as PTP server (https://ohwr.org/project/wr-switch-hw/wikis/home) rather than the Compute Module 4 slave.
