This patch adds basic support for IGMPv3 queries, the default is IGMPv2 as before. A new multicast option - multicast_igmp_version, adds the ability to change it between 2 and 3 via netlink and sysfs. The option struct member is in a 4 byte hole in net_bridge. There also a few minor style adjustments in br_multicast_new_group and br_multicast_add_group. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.
