+ <listitem>
+ <para>A boolean. This setting controls the IFLA_BR_MCAST_QUERIER option in the kernel.
+ If enabled, the kernel will send general ICMP queries from a zero source address.
+ This feature should allow faster convergence on startup, but it causes some
+ multicast-aware switches to misbehave and disrupt forwarding of multicast packets.
+ When unset, the kernel's default setting applies.
