You have described a bug in the switch. You have three choices: 1. Ask the vendor to fix their switch FW. 2. Don't re-start the switch when snooping is enabled. 3. Don't make snooping a persistent setting, but rather enable it via scripting after restarting the switch. I really don't see any linuxptp or kernel issue at all. I definitely will not accept hacks in my project for this kind of switch misbehavior.
