dicates that there are no hosts belonging to the multicast group
in this port, and IGMP Snooping will delete corresponding ports in
the Layer 2 forwarding entries; if receiving response message, it
is not necessary to modify forwarding table.

Fast Leave

When switch monitors the IGMPv2 leave message of designated
group, it does not send the query message. Instead, the switch
directly deletes the corresponding port in the layer 2 forward entry.
Take care when enabling fast leave function in a VLAN, if one of the
multiple hosts in a port leaves multicast group, other hosts of the
same multicast group in the port cannot receive multicast traffic
of the multicast group.
