Subject: [PATCH net-next 0/2] bridge: add support for IGMPv3 and MLDv2 querier

Hi all,
This patch-set adds support for IGMPv3 and MLDv2 querier in the bridge.
Two new options which can be toggled via netlink and sysfs are added that
control the version per-bridge:
 multicast_igmp_version - default 2, can be set to 3
 multicast_mld_version - default 1, can be set to 2 (this option is
                         disabled if CONFIG_IPV6=n)

Note that the names do not include "querier", I think that these options
can be re-used later as more IGMPv3 support is added to the bridge so we
can avoid adding more options to switch between v2 and v3 behaviour.

The set uses the already existing br_ip{4,6}_multicast_alloc_query
functions and adds the appropriate header based on the chosen version.

For the initial support I have removed the compatibility implementation
(RFC3376 sec 7.3.1, 7.3.2; RFC3810 sec 8.3.1, 8.3.2), because there are
some details that we need to sort out.

Thank you,
 Nik
