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.
