H A Dswitchdev.rst331 IGMP Snooping
334 In order to support IGMP snooping, the port netdevs should trap to the bridge
434 when IGMP snooping is enabled for IP multicast over these switchdev network
534 Bridge IGMP snooping
537 The Linux bridge allows the configuration of IGMP snooping (statically, at
541 - when IGMP snooping is turned off, multicast traffic must be flooded to all
549 - when IGMP snooping is turned on, multicast traffic must selectively flow
557 Because IGMP snooping can be turned on/off at runtime, the switchdev driver
562 snooping knob at runtime and require the destruction of the bridge device(s)
563 and creation of a new bridge device(s) with a different multicast snooping
