Hi Florian i forget the details, but there are some difference between VLAN filtering being disabled at compile time, and disabled at runtime. I think the expected behaviour is the same, but the switchdev API usage is slightly different. > +- when IGMP snooping is turned on, multicast traffic must be selectively flowing > + to the appropriate network ports and not flood the entire switch, that must > + include the CPU/management port. 224.0.0.X/32 should always be flooded, IGMP is optional for those groups in the local subnet.
