The RFC explicitly requires maintaining a state variable for IGMPv1/v2 querier version per interface. The implementation only detects v1 queries but doesn't persist this information
 Although the implementation mentions it does not support IGMPv1, but it would be better to support compatibility with IGMPv1.
