If the MLD Querier election mechanism is disabled, the MLD Snooping
querier delays sending General Query messages for 60 seconds after it
was enabled, and if there is no other querier, it starts sending General Query
messages. It stops sending General Query messages when it detects
another querier. The MLD Snooping Querier resumes sending General
Query messages if it does hear another querier for a Query Passive interval
that equals: Robustness * (Query Interval) + 0.5 * Query Response Interval.
