You misunderstand. I am gonna repeat myself: "So basically ptp4l will only work on switch with IGMP snooping if it has been started after the switch, while any restart of switch will cause all PTP traffic to be blocked permanently." So whatever you are blaming for that issue is not my concern, maybe kernel or some module should react to that but does not. Saying that, ptp4l is UNUSABLE on switches with IGMP snooping (many vendors tried and few kernel versions) on devices with older kernels. More tests are required for newer kernels.
