    bridge: Do not send queries on multicast group leaves · 996304bb
    Herbert Xu 提交于
    As it stands the bridge IGMP snooping system will respond to
    group leave messages with queries for remaining membership.
    This is both unnecessary and undesirable.  First of all any
    multicast routers present should be doing this rather than us.
    What's more the queries that we send may end up upsetting other
    multicast snooping swithces in the system that are buggy.
    
    In fact, we can simply remove the code that send these queries
    because the existing membership expiry mechanism doesn't rely
    on them anyway.
    
    So this patch simply removes all code associated with group
    queries in response to group leave messages.
